Once there you see a large scarred area of huge rocks. This is called The Alluvial Fan and is the result of the Lawn Lake Flood of 1982.
On July 15, 1982 at 5:30a.m., Lawn Lakes earthen dam failed, releasing 29 million gallons of water. As the flood rushed downhill four miles to this point, the surging waters picked up boulders and snapped trees. A trash collector heard the waters crashing down Roaring River and called the park Rangers.
It is difficult to imagine that rushing water can move such large boulders.
Tomorrow we are heading toward South Dakota and Mount Rushmore. We will be there for about a week.
More later,
Candy and Johnny
