  • Description 

    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.

    Naked Kill 5.12d 7c 28 IX 28 E6 6b CO : Golden : ... : The Stumbling Block
    The Naked Kill is a testpiece, hard crack splitting a green lichen face just right of the central chimney and left of Razor Blade Titillation. Though only about 50 feet to the ledge, it is on you the whole way. Slightly overhanging and highly technical flared jamming, strenuous finger locks, difficult pro placements -- best describe this proud line.The crack was first freed by Bret Ruckman and Jack Roberts in 1990 at .12b, and apparently has been neglected until my repeat ascent.

    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.

    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.
