About Kelly, WY

The settlement, known today as Kelly, officially formed in the late 1890s as Grovont, but was renamed Kelly in 1909 to avoid confusion with a similarly named settlement nearby. On May 18, 1927 the town was destroyed when a natural dam formed by the Gros Ventre landslide two years earlier collapsed and completely flooded the town. On June 23, 1925 following weeks of heavy rain, approximately 50,000,000 cubic yards (38,000,000 m 3) of rock slid off the north face of Sheep Mountain, and into a valley formed by the Gros Ventre River. The rock formed a large natural dam, backing up the water and forming Lower Slide Lake. The lake and dam eventually stabilized, and engineers determined there was no danger of collapse.
