Bob Horan on FA of Walflower, Canyon Block, Boulde...
The Canyon Block is an obscure, house-sized, 35-foot tall boulder of high quality granite perched high on the North side of Boulder Canyon. Since its walls are South facing, this is a great place to go when it's cloudy, or cold.
The majority of the climbing is low angle and follows natural weaknesses like cracks, seams, and flakes. Most of the harder routes rely on a mixture of pitons, bolts, and traditional gear. None of the routes have fixed anchors, but the top of the block has plenty of trees, and cracks to set up anchors. For those interested in toproping, the top is easily accessed by hiking to the North side.
From the bridge at the bottom of Boulder Canyon, drive 4.7 miles and park at an obvious pullout on the North side of the road next to a large orange, red, and yellow sign that warns people to be careful with matches and fire.
Follow a gully with some exposed water polished granite slabs, and at the top bear right out of the gully and work your way slightly up and left towards the Canyon Block which sits at the top of the hill hidden by some trees.
The entire approach shouldn't take more than 20 minutes.

The right side of the South face of the Canyon Block is split by a fairly pleasant zigzagging hand/finger crack.Scramble into a dihedral at the base of the crack, and move up and right into the crux, stemming and balancing between two widely spaced cracks. Eventually, the difficulties end, and larger holds give way to the top....[more] Browse More Classics in CO

If you see "Long Walk Rock" on the approach, you have gone too far. You can't see the rock on the approach, but you want to cut right when it does not seem like you are in a gully anymore.
