McGregor Mountain
McGregor Mountain, elevation 10,486 feet, as seen from Fall River Road looking across the winding Fall River and a rather broad meadow known as the Horseshoe Park area of RMNP.
A 500-foot thick glacier once covered this valley. As the glacier inched along over thousands of years, it scoured out the distinctive U-shaped valley and carried the rock debris downhill. About 15,000 years ago, the glacier began to recede. At the farthest point of the glacier's advance it deposited a load of rock fragments, called a terminal moraine. The glacier also dropped rubble along its flanks, forming lateral moraines, and the melt water left behind the sediments that formed the meadows of Horseshoe Park.
