The huge, open, light-colored alluvial fan in Horseshoe Park marks a dramatic change. On July 15, 1982, the upstream Lawn Lake dam failed. Flood debris dammed Fall River, eventually forming a temporary lake. Look for other evidence of the Lawn Lake Flood along Roaring River, below Mummy Mountain.
The Lawn Lake Flood of 1982 submerged most of Horseshoe Park, leaving behind the alluvial fan that created "Fan Lake."
A boardwalk through the beaver ponds visible below allows visitors to explore the beaver's watery world.
