Saturday, February 28th, Suzy and I had the pleasure of attending a Fort Collins Group CMC trip, lead by Russ Morgenstern and Susan Tracy, to the Castle Rock Lower Falls, in Boulder Canyon, Boulder, Colorado. Barely 1/8th of a mile up the canyon from Castle Rock, the Lower Falls is an easy 5 minute approach.
As the rest of us geared up at the base of the falls, Russ and Susan set up topropes above the first step for a wide range of climbing possibilities at WI3-4.
This year at least, the Lower Falls ice was in better condition than the Upper Falls, and it had some interesting and fun variations to play with. In this shot, Susan delicately works up through the thin - hollow ice on the left side of the falls.
