Truck drivers Jack and Lyle Tuttle thought the frantic way their truck was flopping around meant the motor had broken loose from the mounts. Driving into the Park, they were halted by huge rocks blocking the road. Renewed shaking, with tons more rocks rolling down the mountainside sent them scurrying for cover behind trees. Lyle took refuge in a tree, where, he later said, the shaking seemed twice as rough. When the quaking stopped briefly, they turned the truck around and were happy to get out before more boulders blocked their exit. 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. [Illustration: Blocked road] His wife, Iris, ran onto the front porch. The porch dropped into the basement. She climbed out, got into the car, and didn’t stop until she reached Bozeman, 90 miles to the north. ■ 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. 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. [Illustration: Fleeing a cabin.] Outside the door she saw a big, 5-foot crevice. As she leaped across it, the house dropped from under her into the lake. More crevices kept opening in the moonlit ground as she walked away from the lake. “Rabbits were skedaddling in every which direction,” she said, but her Malamute dog, Sandy, was so frightened he wouldn’t even notice them. After quite a spell of hiking in the nightmare-like night, she found refuge along with about forty other people at Kirkwood Ranch, which itself was considerably damaged, but a safe distance from the lake. She was safe there, while next day skin-divers, alerted by worried friends, searched her floating house for her body. Later next day she boated past her 9-room home—which contained everything she owned, floating on the lake. “I hope it stays upright,” she said. “My teeth are still on the kitchen counter, right next to the sink.”
