When John was 15 years old a massive earthquake hit Yellowstone National Park. He and his parents were sleeping
The earthquake caused a landslide blocking the river. When the lake rose behind the landslide, all the cabins floated off their foundations. As the lake rose, the prevailing winds blew them east (upstream). They moved about 1 1/2 miles before the lake topped the slide and began to cut a channel. When this happened, the lake dropped and the cabins settled where they were. The photo of him in front of the cabin was two months after the earthquake and shows their cabin off of its foundation.
