The Alluvial Fan in Rocky Mountain National Park is a cascade of water flowing down through a boulder field. It is located off the Old Fall River Road about three miles west of the Fall River Entrance Station. Both the East and West parking lots provide access to the Alluvial Fan. I parked in the East lot and hiked the easy 0.7-mile out-and-back trail that leads to the bottom of the cascading waterfall. The West parking lot has picnic tables and allows access to the top of the waterfall. There are more boulders to climb on this route. There is a 56-foot long bridge that crosses over the river that allows access to the East side.
The Alluvial Fan was formed in 1982 when a dam breached at Lawn Lake and brought down tons of water, trees, boulders and other debris into the valley. This fan-shaped area was formed as a result of all of the debris that was deposited. Today, it is a beautiful waterfall that cascades over a field of boulders. I took my shoes off and enjoyed walking and soaking my feet in the crystal-clear water. The surrounding valley and mountain views make it a nice area to relax and enjoy.
The Old Fall River Road closes during the winter season. read more
