The flood caused by the failure of Lawn Lake Dam scoured Roaring River valley and deposited an alluvial fan of debris in Horseshoe Park.

Lawn Lake Dam was an earthen dam in Rocky Mountain National Park, United States that failed on July 15, 1982, at about 6 a.m., in an event known as the flood of 1982. The sudden release of 30 million cubic feet (850,000 m3) of water resulted in a flash flood that killed three people camping in the park and caused $31 million in damage to the town of Estes Park, Colorado and other downstream areas.
