This is a set of 3 canyons that are the drainages of the South, Middle, and North forks of the St. Vrain River. The greatest bulk of the climbing to date is in the South Fork. The rock is granitic and at times on the coarser side. There are a variety of routes here, some traditional, some sport, even some ice/mixed
. Most of the routes are shorter here, maybe up to 5 pitches in length. There is still a decent amount of rock to explore here. While there is some friable rock in places, the bulk is good quality. Poison ivy does tend to flourish in spots here, so the sensitive should be aware.
Most will drive up US 36 or CO 66 west to Lyons. From there, the forks diverge. The South and Middle Forks are accessed off of CO 7. The North Fork is accessed off of US 36.

This is a classic boulder problem that comes out of the roof. Stand start matched on a good sloping ledge, and bust into a juggy incut on the roof. Work over the lip through some right hand slopers and left hand sidepulls to gain the topout (crux). It looks like a lower start may be possible, but it would be really, really hard....[more] Browse More Classics in CO
