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.

Razor Blade Titillation was one of the original routes on The Stumbling Block and represents one of the few contributions to Clear Creek by the consumate Brett Ruckman. Most climbers will recognize Brett for the huge, prolific effort he and his brother put in to climbing at American Fork and at Rifle. I have only rarely had the opportunity to watch Brett climb, but he is a wonderful and powerful climber, moving with the deliberate pent-up power of a great athlete.

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.
