Location: 40o 24' 37" N, 105o 38' 07" W.

A flash flood swept down this valley west of Estes Park, Colorado, on the outskirts of Rocky Mountain National Park, scouring the valley walls in the distance and leaving large boulders behind. At its peak, the flood was a soupy mass of mud, sand, water and rocks, more like wet cement than water.
