Remains of the collapsed Teton Dam

The Teton Dam was a federally built earthen dam on the Teton River in southeastern Idaho, set between Fremont and Madison Counties, USA which when filling for the first time suffered a catastrophic failure on June 5, 1976. The collapse of the dam resulted in the deaths of 11 people and 13,000 head of cattle. The dam cost about USD $100 million to build, and the federal government paid over $300 million in claims related to the dam failure. Total damage estimates have ranged up to $2 billion. The dam was never rebuilt.
