In many respects The Stumbling Block is a terrific crag, if only the approach were more user friendly. The routes face South and South-East, so the crag does well in the summer months, and can be quite cool in the winter. The rock is exceptional by Clear Creek standards being very, very solid. Presently, there are enough routes to keep a party busy for a day, but there is [not much] moderate in place. What it does have, however, are some of the best routes in Clear Creek Canyon.

Getting There

About a quarter of a mile upstream after leaving tunnel one, the road takes a curve to the right. At just this point, look uphill to the right, the North side of the canyon. The Stumbling Block is the crag on the right boasting a gorgeous yellow wall. Park on the South side and find a rough drainage with a steep trail. The trail heads directly uphill for several hundred yards before cutting due West to the crag. Be ever vigilant. Anything that you kick off the trail will hit the road. The whole slope is steep and still has a fair amount scree lying around.

I've only been up here once, but the approach gully with two aspens next to the road was significantly more solid, safer, and more enjoyable than the dirty, loose gully to the left. Oct 18, 2015

It says in the description that there is nothing "moderate" at the Stumbling Block. This is not true. There is a 5.6 and a 5.7. They are short, but they are moderate. Sep 14, 2013
