Flagstaff Mountain Bouldering Professional Review and Guide
"Flagstaff Mountain, with its easy access from Boulder, is Colorado’s historic bouldering area. Numerous boulders, with a wide variety of problems and difficulties, scatter across the upper flanks of 6,872-foot Flagstaff Mountain, forming a playground for both the beginner and expert boulderer. The boulders, composed of coarse conglomerate sandstone, offer lots of moves with pebble-pinches, shallow sloped dishes, sharp flakes, finger pockets, and gritty edges. The granular rock quickly shreds fingertips, especially after multiple attempts on a problem."
