Gros Ventre landslide
The Gros Ventre landslide (
The landslide occurred on June 23, 1925, following melt from a heavy snowpack, several weeks of heavy rain, and earthquake tremors in the area.
On May 18, 1927, part of the landslide dam failed, resulting in a massive flood that was six feet (1.8 m) deep for at least 25 miles (40 km) downstream. The small town of Kelly, six miles (9.7 km) downstream, was wiped out, killing six people. It is one of the world's largest known examples of recent mass wasting events aside from volcanic eruptions. Slide Lake is now much smaller than before the flood.
Today, the landslide is partially reclaimed by the surrounding
Etymology
