Koko Kosila. Ever dream about being the rock?
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 the beautiful, large, right-facing dihedral to climber's left of Upside The Cranium. The Hubbell guidebook lists this climb as 5.10a/b. We clipped the first two bolts of UTC to protect the start. The majority of the start and lower portion of the dihedral is 5.8/9 climbing easily protected with small / medium gear. Over the last 25-30 feet the dihedral arcs dramatically to the right across a steepening face. This makes for a fairly strenuous jamming / stemming /...[more] Browse More Classics in CO
