Kelly Wyoming is in Grand Teton National Park and borders on the National Elk Refuge witch in winter is home to thousands of Elk and a heard of bison. The views of the east side of the Tetons are unsurpased from any other town in the region. In summer bison roam all over the area.

Kelly Wyoming was originally called Gros Ventre (Grovont). It was named to honor Bill Kelly, a local sawmill owner and rancher. In 1925 50 million tons of rock, soil, and other debris, including some ancient trees, slid off Sheep Mountain and dammed the Gros Ventre River and formed Slide Lake.

In 1927, the upper part of the dam gave way. Kelly residents had only a few minutes to get to higher ground and watch the fifteen foot wall of water sweep their town away, leaving only the church and the schoolhouse behind. Six people lost their lives in the flood.

The Slide is still a pretty amazing site as is the river bottom that to this day is strewn with giant boulders that first slid out of the mountain only to be washed down river by the flood of the broken dam.
