Submitted by: Jean Ensign Orton Location at time of earthquake: Campground at Rainbow Point on Hebgen Lake, MT __________
Rainbow Point, six miles from Hebgen Dam on Hebgen Lake, is our favorite camping spot because of the great fishing. That's where we experienced the August 1959 earthquake.
Submitted by: Stuart Loosli Location at time of earthquake: Idaho Falls, Idaho __________
On the evening of August 17, 1959, I had returned home from a movie with my future wife, Jessie. While decompressing in our family/TV room in the basement of my parent's home at 441 Ninth Street, Idaho Falls, Idaho, I was watching a "TBA" program on the television. Most TV shows were "TBA" - To Be Announced- in those days. Suddenly I felt a deep earthbound thump and then the hanging ceiling lamps with the green lamp shades and very dim lamps began to sway. Reclining on the couch did not seem advisable. I ran up the stairs and into the backyard to see what else might be happening. The Atomic Energy Test Site always lurked on the horizon to the west. Outside, a few dogs were barking. The wire cable suspended street lights and the overhead phone and power cables in the alley behind the house were bouncing and swaying back and forth. Suddenly I realized that perhaps an earthquake had occurred or was occurring. I remember being enveloped by an eerie uncomfortable sensation, but no real sense of imminent doom or danger. The questions of What? Where? When? How? And Who? wouldn't be answered until later or even never. I have always felt a bond with that event, the people affected and that part of our Intermountain history.
Submitted by: Sheena James Location at time of earthquake: Home in Idaho Falls, Idaho __________ I was asleep in my bedroom on the main floor of our house in Idaho Falls. I heard a loud bang, felt a shaking, and all the lights in the house came on. I went into the kitchen. My father was trying to figure out who turned on all the lights. We thought that some of my brother's friends had been messing around. We didn't know until the next day that it was an earthquake.
Experience of: Yellowstone National Park rangers and truck drivers Location at time of earthquake: West Yellowstone entrance to Yellowstone National Park __________
When the quake hit, summer Alternate Rangers Fred Tim and Lamont Herbold were on duty at the West Yellowstone entrance of Yellowstone National park. They had just cleared a semi-load of Pres-to-Logs. As the truck pulled on through the gate, the plywood gatehouse shook so violently, with the lights flashing off and on, that Herbold shouted,
Experience of: Jerry Yetter, manager of motel near West Yellowstone Location at time of earthquake: Duck Creek Cabins near West Yellowstone __________
In the confusion that followed when the first shock hit, Jerry Yetter, who operates the Duck Creek Cabins near West Yellowstone, jumped out of bed and knocked on all the cabin doors to warn the occupants of the quake. Only after he'd finished the job did he realize that he was wearing no clothes at all.
Experience of: Rolland Whitman Location at time of earthquake: Near Duck Creek Junction north of West Yellowstone, MT __________ Just west of the Duck Creek Junction of highways 1 and 191, the first shocks wakened Rolland Whitman as it sent dishes and furniture crashing to the floor. When he couldn't reach his wife's folks in West Yellowstone, 10 miles south, by phone, he rushed his wife, Margaret, and their six children into the car, started out, and immediately crashed over a 13-foot drop-off scarp that the quake had jutted up between his home and the highway.
Experience of: Mrs. Grace Miller, manager, Hilgard Fishing Lodge Location at time of earthquake: Hilgard Fishing Lodge; Hebgen Lake, Montana __________
On the night of the quake Mrs. Grace Miller, a widow who, in her seventies, is still sprightly enough to run, single-handed, the Hillgard Fishing Lodge cabin and boat rentals on the north shore of Hebgen Lake, found herself suddenly wakened about midnight. She didn't know what was happening, but she felt she had to get out of the house. She threw a blanket around herself. The door was jammed, and she had to kick to get it open.
Experience of: caretaker family at Blarneystone Ranch Location at time of earthquake: Blarneystone Ranch near epicenter __________
At the Emmett J. Culligan place, dubbed the "Blarneystone Ranch," the Santa Barbara water softener tycoon spent hundreds of thousands of dollars building a refuge from the possibility of atomic attack.
Experience of: Irving J. Witkind, U.S. Geological Survey geologist
Location at time of earthquake: Geological Survey camp trailer located north of Hebgen __________
The only man who was enthusiastic about the earthquake from the start was geologist Irving J. Witkind of the U.S. Geological Survey, who was living in a trailer on a rise to the north of Hebgen Lake, above the Culligans and Parade Rest, while he surveyed and mapped the area.

Location at time of earthquake: Geological Survey camp trailer on hillside near __________
The Hebgen Lake, Montana, Earthquake of August 17, 1959 By Irving J. Witkind During the early and middle parts of August 1959 the weather was nearly perfect--cool sunny days and clear calm nights. On the night of August 17 the moon was full. Tourists crowded the area, so much so that late travelers through the Madison River canyon could find no available site at any of the campgrounds and reluctantly continued on. The first earthquake shock came at 11:37 p.m., after most of the residents and tourists were abed. It is uncertain just how long the earth trembled--estimates range from about 5 seconds to as much as several minutes--but those who experienced the violent shaking will certainly never forget it. Some nearly panicked; others showed great courage. Our Geological Survey camp consisted of two house trailers parked on a small hill near the Blarneystone Ranch. Mr. and Mrs. J. B. Epstein occupied one trailer; I occupied the other. A day after the earthquake, Mrs. Epstein wrote this to her friends: All of a sudden the trailer began to shake violently up and down and back and forth. I thought at first that Jack was fooling around and shaking the trailer, but in a split second I looked around and saw: l. Water pouring out of the wash basin. 2. All dishes, groceries, and clothes falling out of the cabinets. 3. The gasoline lantern hanging from the ceiling, swinging in a 2-foot circle, and looking as if it would fall any minute. If it did it would have set the whole trailer on fire. There were fantastic rumblings. The farthest thing from my mind was an earthquake. In this same split second I thought that the 100-pound propane tank outside the trailer was starting to explode and that's what caused the noise and shaking. In pure horror and fright I dashed out the door and screamed for everyone to follow and run as far away from the trailer as possible. Jack was still in the trailer, trying to stop the lantern. He got beaned on the head with it, gave up, and came charging out. He had realized from the first that it was a quake. My complete horror came after I hit the ground and found that it was no better than in the trailer. The solid earth, "terra firma," was like a glob of jelly. I was frantic--there was nowhere to get away from the fantastic sensation. Jack screamed not to run near the woods because trees were toppling all over. We could hear loud rumblings due to rock slides and landslides in the mountains. At the time of the earthquake I was asleep in my trailer. As I later wrote to my wife, "I went to sleep about 9:30 p.m. and was awakened by the frenzied jiggling of the trailer. Things were falling from shelves all over the place. I thought that the trailer had somehow come off its jacks, jumped the chocks, and was rolling down the hill. I scrambled out the front door determined to stop the trailer, no matter what, although I had no idea as to how I would go about it. When I got outside, the trailer was in place, but the trees were whipping back and forth and the leaves were rustling as if moved by a strong wind--but there was no wind. I knew right then that it was an earthquake. I could hear avalanches in the canyons behind me, and could see huge clouds of dust billow out of the canyon mouths. Jack Epstein, who was awake at the time of the earthquake, says he heard a deep rumbling in the earth. I noted the time of the first shock, and kept track of the major aftershocks for about 20 minutes before I decided to visit the Blarneystone Ranch and see if they needed help. I drove down the hill toward the ranch. About a quarter of a mile from camp I came upon a large new fault scarp that cut across and displaced my access road. The Blarneystone Ranch was severely damaged (fig. 6). When John Russell discovered that the doors of his apartment there were jammed shut and that he and his family were trapped, he broke a window and used it as an exit. Others in the main dwelling made their way to safety through once-orderly rooms that were now a scene of displaced and overturned furniture, fallen pictures, and plaster. The Parade Rest Ranch, about half a mile to the south, was also damaged, although not as severely. Mr. Wells Morris, Jr., the owner, was suddenly awakened by the distinct sensation that his bed was falling from beneath him in short spasmodic jerks. Also awakened by the quake, a family in a motel on U. S. Highway 191 hastened into their car and raced southward, trying to escape, only to drop off a new fault scarp which crossed the highway about 500 feet from the motel. The car turned over and was demolished; the family returned to the motel, unharmed. A rancher hurrying to help his neighbor drove off a new scarp about 100 feet from his house. His car remained on end all night. Shortly after the earthquake, the occupants of a small house trailer parked near the north shore of Hebgen Lake discovered to their horror that the lake which had been 50 feet away was now swirling around the trailer, and rising. The couple made their way out, waded through the water to higher ground, and then watched the trailer float away. The next morning only the open hatch in the rooftop could be seen, some 100 feet offshore. At Hilgard Lodge, about a mile southeast of Hebgen Dam, the earthquake and the accompanying surges of the lake wreaked havoc (fig. 9). The main dwelling and a group of connected motel units were built on a broad sloping alluvial cone at the northeast edge of the lake--a sector of ground that dropped about 10 feet during the earthquake and was broken by many small scarps and gaping fissures. All the buildings were tilted and knocked askew, then lifted and dropped by a wave of water that moved toward the dam. Mrs. Miller, the owner, was asleep at the time of the quake. Suddenly aware that her house was sliding into the lake, she scrambled out with great difficulty and, dazed and shocked, stumbled across scarps and fissures in a rough sagebrush pasture to the Kirkwood Ranch, more than a mile away. George Hungerford, foreman at Hebgen Dam, and Lester Caraway, his assistant, were awakened by the major shock and within moments recognized it as an earthquake. With their wives, they hurried to a water gage downstream from the dam to see if the river flow showed that the dam was leaking. As they neared the gage, Hungerford heard a roar. He glanced up to see a wave of water about 4 feet high moving down the river. Fearing that this meant the collapse of the dam, he returned to his house on the highway above the gage and tried to telephone a warning, but the line was dead. The two couples then drove toward the high ground near the dam and arrived there at about 11:55 p.m. The moon was obscured by dust, and it was very dark. The water had withdrawn from sight, but they noticed that the downstream side of the dam was wet. Then, before they could see it, they heard water again; it was coming down the lake. They climbed out of the way and watched the water rise, overtopping the dam by about 3 feet. After 5 or 10 minutes it receded, then disappeared from sight. "All we could see down the dam was darkness again," Hungerford recalls. The crest of the dam was again submerged in 10 or 15 minutes, but this time by less water, and the water receded sooner. In all there were four surges over the crest. Between them, Hungerford and Caraway could see no water on the upstream side, even once when they ran out onto the dam. The water in Hebgen Lake had been sloshed about like water in a bathtub, and it continued to oscillate, though less violently, for at least 12 hours after the quake (Myers and Hamilton, chapter I). Many of the campers downstream from the dam were slow to realize what had happened. They woke and looked about them, confused, but the aftershocks alerted most of them to the danger. Fearing that the dam would break, they abandoned their trailers and fled by car to higher ground. Among them was the Lewis Smith family of Greeley, Colo., who were sleeping in a small house trailer in the Beaver Creek Campground, about 2 miles downstream from Hebgen Dam. Awakened by the violent shaking of the trailer, Mr. Smith called to a neighbor and asked what had happened. An earthquake, he was told--and the dam was not far upstream. Smith decided to evacuate his family and leave the trailer behind. When he reached State Highway 499 he had two choices. He could turn northeast and drive toward the dam for about 2 miles to the high ground on which the dam was built, or he could turn southwest and drive down the Madison River canyon for about 5 miles and then leave the confines of the canyon for the open country west of the Madison Range. Believing that the dam would break at any moment and unwilling to risk driving toward it, Smith turned southwestward, down the canyon. Three and a half miles from the campground a huge boulder blocked the road, but Smith was still unwilling to drive the other way. The family left their car and climbed to higher ground, where they spent a cheerless night. Boulders were crashing down the mountainside, but not until daybreak did they realize that the route was blocked by a great landslide. Early the next morning, Smith returned to his car and listened to a radio broadcast in which the collapse of Hebgen Dam was declared imminent. He drove his car part way up a small hill, then rejoined his family. The Smiths were rescued by helicopter that afternoon; their car was gradually inundated as the river, penned up behind the Madison Slide, rose to form Earthquake Lake (frontispiece). For some travelers the night of August 17 was more tragic. Mr. and Mrs. F. R. Bennett and their four children, en route from their home in Coeur d'Alene, Idaho, to Yellowstone National Park, camped that night in the Madison River canyon near Rock Creek Campground, which was later partly buried by the Madison Slide. The parents were sleeping in their small house trailer, and the children were in bedrolls on the ground nearby when Mrs. Bennett was awakened by a loud noise. "Some time later" she heard a great roar and, alarmed, went with Mr. Bennett to check on the children. Just as they left the trailer a tremendous blast of air struck them. Mrs. Bennett saw her husband grasp a tree for support, then saw him lifted off his feet by the air blast and strung out "like a flag" before he let go. Before she lost consciousness she saw one of her children blown past her and a car tumbling over and over. Her son Phillip, 16 years old, was buffeted about by the air blast and immersed in water, but somehow, with a broken left leg, he managed to crawl into a clump of trees, where he burrowed into the mud for warmth. He and his mother, sole survivors of the family, were rescued the next morning. Rev. E. H. Ost and his family were among the survivors at Rock Creek Campground. Awakened by the first tremor, the family left their tent. As they stood in the bright moonlight, about 20 seconds after being aroused, they heard a tremendous grinding noise and, with it, the sound of water. No wave of water was moving downstream; instead, Rev. Ost saw water moving upstream. He shouted to his family to hang onto trees. His daughters, alerted by the call, scrambled up slope. Water swirled through the campground, rolling and tumbling their car about 50 feet upstream, but Rev. and Mrs. Ost held firm to the trees and soon were able to pick their way out of the debris. With other survivors, they climbed to higher ground. Dawn revealed the east edge of the Madison Slide about 100 yards from the Osts' former campsite. By 6:00 a.m. all the cars in the campground were submerged beneath Earthquake Lake. The house trailer of an elderly couple, Mr. and Mrs. Grover Mault, of Temple City, Calif., was carried some 200 feet upstream in the wave created by the Madison Slide. The water rose rapidly as the Maults tried to escape from the trailer, so rapidly that by the time they made their way to the door the trailer was almost completely submerged. They managed to get out and climb first onto its roof and then, as the trailer was inundated, into a nearby pine tree. The ever-rising water forced them to climb higher. Several times, when the boughs broke under their weight, they fell into the lake. Each time they climbed back. Just as daylight was breaking, they were rescued, after 5 hours in the tree. At Ennis, Mont., about 50 miles downstream from Hebgen Dam, the major tremor aroused many of the residents. A few went outside to see what had happened; most merely went back to sleep. At about 2:45 a.m. a message reached Ennis that the dam had failed or was about to fail, and the authorities immediately began to alert the residents. Sirens sounded, and people went from house to house warning their neighbors and friends. The word swept through town. All residents were urged to move to higher ground as soon as possible. Most took a few prized possessions and drove to a high terrace at the west edge of town. By 4:00 a.m. Ennis was nearly deserted, and as the night passed may residents moved to still higher ground farther west. By dawn a large field in this new area was covered with cars. The threat of flood still hung over Ennis on August 18, and by midmorning roadblocks had been established on State Highway 499 leading to the Madison River canyon. As the threat lessened, many residents wished to return to their homes, but the town officials, fearful that Hebgen Dam still might collapse, issued an official evacuation order to prevent their return. Most of the populace spent the rest of the day and that night camped out. The order was retracted on the afternoon of the 19th, and the residents returned to Ennis on the basis of a standing alert. The warning signal was to be the sounding of the siren. This was never used, for Hebgen Dam held firm. At West Yellowstone, which was much closer to the epicentral area and therefore more intensely affected by the major shock than Ennis, the fear of additional severe shocks prevailed. Most of the residents left their dwellings at the time of the major shock and got into their cars. An amateur radio operator radioed: "The pavement looks like it is coming toward me in waves a foot high." The aftershocks kept people away from buildings, and many spent the night in their cars. In the early morning large numbers of tourists left the area via U. S. Highway 20 to Idaho--the only route not blocked. The earthquake was felt in most of the surrounding communities as a moderate rolling and pitching motion. At Bozeman, Mont., about 60 miles north of the epicentral area, the major tremor jostled the community awake, and some residents heard a low rumbling roar in the ground. A few of the more curious went outside; most of the others, satisfied that their lights and telephones were still working, went back to sleep. At Butte, Mont., about 100 miles northwest of Hebgen Lake, the motion reminded one reporter of "negotiating a rough patch of water in a small boat." The tremor was first felt as a slight shaking which worsened and lasted about 30 seconds. At Ashton, Idaho, about 55 miles south of Hebgen Lake, most of the populace was shaken awake but no one was injured, nor was there any serious structural damage.
Experience of: Robert M. Burley Location at time of earthquake: Beaver Creek Campground, Madison River Canyon __________
My Wife and I arrived at Beaver Camp ground, a favorite camping spot on the Madison River, at approximately 10 o'clock on the night of August 17. We set up our tent and had just gone to sleep when my wife was awakened by the earthquake. She woke me up screaming, "A bear or something is shaking our tent!" We both jumped up and stumbled through the tent door. At first, I thought it might be a violent wind storm; but when we got outside, we immediately realized what it was. Neither one of us could stand up, and we fell to the ground, clawing for something to hold onto. My wife thought it was the end of the world, and I was about ready to agree with her.
Location at time of earthquake: Apartment in Bozeman Hotel
__________ At 11:37 p.m., Monday, August 17, 1959, when the first hard jolt of the earthquake struck, I was enjoying some much-needed sleep in my apartment in the Bozeman Hotel, where my professional and business offices are located. After being jolted from bed, I immediately switched on the radio to catch any news, but at that time it was too early for any reports. I dressed as quickly as possible and went down to the lobby where most of the guests were gathering, many still in their night clothes. Some were badly frightened, and a few on the verge of hysteria. After doing what I could to calm them my first thought was for the welfare of my employees at West Yellowstone, where I own the Stagecoach Inn, and also maintain a professional office. I tried to call but the telephone lines were down. As the night wore on, the radio reports gave only a few vague, contradictory details, but confirmed that there had been an earthquake of major proportions. Through the sheriff's office, which was in communication via short-wave radio, I learned the shock centered in the west Yellowstone area, and all roads to this vicinity were blocked and several bridges out. There was also the report that Hebgen Dam was leaking badly and the Madison River rising. Ennis, Three Forks, Trident, and Townsend, small towns down the river, had been warned to evacuate. Before dawn several families from Trident registered into the hotel, and I later learned that many families from these towns spent the remainder of the night huddled on the hills outside if their respective towns. At dawn, equipped with my medical bag, I chartered a plane from Flight Line Inc., piloted by Bob Winterowd for the flight to West Yellowstone. We attempted to fly directly toward Ennis, but encountered a severe thunderstorm and were forced to fly back and up the Gallatin Canyon and over the mountains, coming into the Madison at the lower end of the Canyon. We had had no report of a slide and as the canyon came quickly into view we were completely appalled. The mountain on the south had fallen across the canyon. It was hard to comprehend the immensity of the slide and damage it inevitably had done. We circled down as close as possible. The whole area seemed to be green, due to uprooted trees laying crisscrossed like match sticks, except for the top part of the slide that had rolled up the opposite wall of the canyon like a giant ocean breaker. We estimated it to be one mile long and 250 to 300 feet deep where the road, river, and Rock Creek Campground had been. It was obvious that any people in the immediate vicinity had been killed or injured. On the upper side a lake was beginning to form. It had already reached the tops of some of the smaller evergreens along the river bank adjacent to the slide. Below the slide the river bed was nearly dry for some distance. However, from the air, it was apparent why the report that the river was rising rapidly and evacuation notices had been issued down river, since the water had been forced from beneath the slide with terrific force thereby temporarily greatly increasing the flow of water. At a short distance, on the highest ground they could reach, a small group of people were gathered. They were desperately waving anything available to attract attention. We circled low to indicate that we had seen them and were aware that they were in desperate need of help, and also to try to determine if there were any injured among them. As we went farther up the canyon there was a large group of people, cars, tents, and campfires. As we approached Hebgen dam we could see the extensive damage to the dam. There were large cracks in the concrete core, the spillway was cracked and chunks broken out, and there was considerable damage to the dirt fill below the concrete. Another large group of people and cars was gathered on the roadway, where it widens out at the north end of the dam. Hebgen Lake, which was then very muddy and rough, was covered by thousands of logs which were just barely floating. The road just above the dam had completely disappeared into the lake for approximately 100 yards. The top of a house and other debris were floating where the road had been. Two large fault lines were clearly visible on the mountain. One was a short distance above the lake, the other higher up. Farther up the lake there were two more areas, each approximately 100 yards long, where the road had disappeared into the lake. The upper, or south, end of the lake had raised out of the water, and boat docks had either been swept away or were marooned in the mud far from the water. Cabins previously located on the edge of the lake were now hundreds of feet from shore. We later learned that this end of the lake had raised 8 feet sending cascades of water in the form of huge tidal waves over the dam, thus adding to the formation of the new lake. The fate of the people completely trapped between Hebgen Dam and the slide, a distance of seven miles, was indeed precarious. The dam was expected to go out momentarily, there was danger of additional slides at any time, and waves with each new major tremor. There was no means of escape except by rescue by helicopters. As we flew on toward West Yellowstone we saw where the fault in the earth crossed the highway at Duck Creek. Abutments to all three bridges were out. As we approached West Yellowstone, we could see that considerable damage had been done to the town. Chimneys had fallen and many buildings were badly damaged. When we landed at the airport we found many people gathering there. They were as yet unaware of the tragic situation down the canyon. From the airport I caught a ride the few blocks uptown to the Stagecoach Inn. There I found the few employees and guests who had not evacuated south into Idaho, huddled around a campfire under some pine trees across the street from the Inn. I spoke briefly with them and was told that the Inn had suffered serious damage. However, at that time, I was more concerned with the sorry plight of the people trapped between the dam and the slide. The only employee left in the Inn was the manager, Jane Winton, who is a registered nurse. Without bothering to inspect the Inn for damage, I asked her if she was willing to fly back to the slide area with me to render what aid we could. She replied something to the effect, "that it would be a relief." We hurriedly gathered additional medical supplies and returned to the airport, where I asked Bob Winterowd if he was willing to fly back and attempt a landing. His reply was, "If you're willing, so am I." We flew back and managed to find a field large enough to land on at the Watkins Creek Ranch, located on the south side of the lake about three miles from the dam. We walked about half a mile down the lake toward the dam through mud and debris thrown up by the tidal waves to a place where people were dragging their boats higher out of the water, which had risen eight feet at this end due to the tipping of the lake. These people believed the dam to be going out, and were reluctant to lend a boat. Finally, a young fellow, whose name I never learned, volunteered to take us across in his motor boat. It was impossible to dodge the trees and other debris, so we just went over the top of them, and prayed we wouldn't hit a snag. It was approximately 3 miles to the end of the dam where we landed. We then had to cross the cracks and crevices in the dam. The ground was still quivering. A nurse, Mildred Greene, of Billings, Montana, who has since been featured in a Reader's Digest article about the quake, met us at the other end of the dam. She told us that no one had been there, and that they had had no word from the outside since the quake, more than 8 hours earlier. She had been camping in the area with her family. They had been a little above the major slide, so had not been injured. She had gathered all the more seriously injured into the area just along the highway end of the dam. There were 16 seriously injured, and she had them in the back of the station wagons, except for one couple in a fishing trailer. Among the injured was a woman whose left arm was nearly severed in two places; she had suffered a crushed chest and was in severe shock; a woman who had suffered three deep body wounds and a severe blow on her head; a man with painful internal injuries, a broken collar bone and severe lacerations; a man with deep lacerations over 90 percent of his legs; a girl with a crushed ankle; a woman with a broken vertebra; a small child with a gash over her eye, which at the hospital, required 32 stitches to close. There were many others with less severe injuries. Mrs. Greene had done wonderful work in the absence of drugs, medications, and even bandages. Not only that, she had kept them all under control and calm and quiet. We were there for one and a half to two hours, helping with the medications which we had brought for pain and shock. All these people were badly in need of hospital care, so as soon as I had done everything I could, we recrossed the lake, hiked to the plane, and returned to West Yellowstone to alert the hospital via short wave, and help set up the air rescue. The injured couldn't be taken out by boat, since they were too badly hurt to be transported that way, and the lake was too dangerous. No roads were open so it was a matter of getting them out by helicopter. Shortly after noon, an Air Force helicopter and other planes arrived. The helicopter flew the first load of injured to the West Yellowstone airport where they were immediately loaded onto the floor of a converted B-18, and flown to Bozeman. The helicopter flew the first load of injured to the West Yellowstone airport where they were immediately loaded onto the floor of a converted B 18, and flown to Bozeman. The helicopter shuttled back and forth from the dam to the airport, and planes from the Johnson Flying Service flew these additional loads down. There was a fleet of station wagons at the airport there to rush them to the hospital. The 16 most seriously injured were in the Bozeman hospital by early afternoon. I made several trips down and back with the planes. Two of these injured later died at the hospital. If the medical attention had reached them sooner they might have lived. However, several others might have died if medical attention had been longer delayed. While we had been making our hazardous crossing of the lake, above the shaky dam, the old World War II slogan, "Is this trip really necessary?", kept popping into my head. As it turned out, it was, and I shall always be glad I made it.
Experience of: R. F. Bennett family Location at time of earthquake: Campground in Madison River Canyon __________
One of the more tragic incidents involved the F.R. Bennett family of Coeur d'Alene, Idaho. Mr. and Mrs. Bennett and their four children, en route to Yellowstone National Park, reached the western end of the Madison River Canyon late in the afternoon of August 17 and decided to spend the night there. Mr. and Mrs. Bennett occupied their house trailer, while the children slept in bedrolls nearby. The Bennetts were awakened by the jiggling of the trailer and wondered what had caused it. Some time later, Mrs. Bennett recalls, she heard a tremendous roar, and she and her husband, alarmed, left the trailer to check on the children. Suddenly they were struck by a violent blast of air. Mrs. Bennett saw her husband grasp a tree for support; then as his feet were swept out from beneath him, he was strung out "like a flag" for a moment before his hold was broken and he was blown away. Before Mrs. Bennett lost consciousness, she recalls seeing one of her children blown past her, and a car being tumbled along by the air blast
Experience of: Lewis Smith family Location at time of earthquake: Beaver Creek Campground, Madison River Canyon __________
The Lewis Smith family of Greeley, Colo., camped at the Beaver Creek campground, about two and a half miles downstream from the dam, were awakened by the major tremor. Cognizant of their precarious position below the dam, Smith hurried his family into their clothes, and drove away, abandoning his house trailer. At highway 287 he had two choices. He could turn northeast and drive toward the dam for two and a half miles until he reached the high ground near the dam; or he could turn southwest and drive five miles down and through the Madison River Canyon.
Experience of: Rev. Mr. E.H. Ost and family Location at time of earthquake: Rock Creek Campground; Madison River Canyon __________ When the slide came to rest, its northeastern (or upstream) edge was about 100 yards away from a campsite occupied by the Rev. Mr. E.H. Ost and his family. The Rev. Mr. Ost and his wife were awakened by the major tremor and stepped out of their tent to see what had happened. They stood in the moonlight for about 20 seconds looking about; then suddenly they heard a terrifying grinding and roaring noise intermingled with the sound of rushing water. Alarmed, Mr. Ost at first thought that a wave of water was coming downstream. None was, but when he glanced downstream he was astonished to see a wall of water racing toward him! He called to his family to hang onto trees and he and his wife did so while the water swirled around them. Their daughters fled about 50 feet and were not touched by the water. When the wave had passed, Mr. Ost and his family struggled up the mountain flank away from the rising water. They were joined by other survivors and all were rescued the next day.
Experience of: Mr. and Mrs. Grover Mault Location at time of earthquake: Rock Creek Campground; Madison River Canyon __________ Once the valley was blocked, the waters that crested Hebgen Dam as a result of the seiche, plus the waters normally released through the spillway at the dam, were impounded east of the slide and Earthquake Lake began to form.
Mr and Mrs. Grover Mault of Temple City, Calif., were almost drowned by the rising waters of Earthquake Lake. They spent a miserable, forlorn, and frightening night in the branches of a tree, watching the waters of the new lake slowly rise.
