This is an obscure, granite crag on Boulder County Open Space land which doesn't quite fit into Boulder Canyon or Upper Dream Canyon. It also is known as Sugarloaf Dome. It lies off the Sugarloaf Rd, a home to a small, intriguing community. It is probably not worth the time or energy or potential aggravation to find this crag. Once, it hosted about 15 moderate routes in the 8 to 12b range. It has been the site for odd bolt bashing...possibly by governmental employees, so be careful of relying upon any fixed gear for protection.
It is described in Rossiter's excellent 1999 Boulder Canyon guidebook on p. 24-5 & Rolofson's classic 1995 Boulder Climber's Guide p. 87-8.
These routes include: A. Vector, 10. B. The Simpsons, 11, chopped. C. Center aka Permanent Protection, 10+, chopped. D. Malamute With An Attitude, 9+, chopped. E. Old Route, 8. F. Love to Regret It, 9+. G. OJ Flake, 9. H. Sultry, 10. I. Roof Route, 11-. J. Broken Camera Blues, 11- R. K. C'est Chouette aka Crack to Face, 10. L. Suspended Man, 12, chopped. M. Thanks Bill Left, 11- R. N. Thanks Bill Right, 8 or 10-, chopped.
Drive up CO 119 aka Canyon to Sugarloaf Rd about 3.8 miles past Elephant Buttresses/Dome Rock. Go north about 0.9 miles, turn right on Betasso Preserve Rd, go another 1/2 mile or so. Park. The trail goes to the top of the crag. Climb around either side of the crag to its base.
Mountain Project's determination of some of the classic, most popular, highest rated routes for Bummers Rock:
This is the furthest East (on the right as you are looking at the cliff from the bottom) route on the wall. It starts on a flat area at the very base of the granite slabs. The first pitch follows a slab to the anchors that is broken in two places by horizontal seams. The first pitch is easy 5.7 or so slab climbing with 2 bolts to an anchor. The next pitch continues up the face to the left (follow the bolts). There is a mantle move that I would call the crux at the second bolt of the second pitch...[more]Browse More Classics in CO
Went there, based on '95 sport book listings, in June 2006. It seems to us that most of the bolts have been chopped by the city. We could not find the older listed routes, except for on the east side of the crag. Thanks Bill (var. 10a, and left side 11a) were worth doing, but there are no anchors at the top. All in all, not worth the walk, unless you like views to the south (Boulder Canyon/Magnolia Road) and no people.
