Tuesday, June 23, 1925. The Gros Ventre Landslide.

The Gros Ventre landslide near Jackson occurred following heavy rains and a 4.0 magnitude earthquake.  Approximately 38,000,000 m3 (1.3×109 cu ft) of sedimentary rock came down the Tetons, dammed a river, and created the Lower Slide Lake.  The dam partially failed in 1927, wiping out Kelly.
