The same bouldering area can be found at the main Penitente parking area. Be cautious not to claim any first ascents on this feature...they have probably been done (perhaps by Estes Park legend Chris Banks). Mantle problems abound. Gill would be proud. Look for the Flying Dumpkin, Ring around the Toilet, and Souper Pooper.-JM
yes, these problems HAVE been done, years ago, on an identical boulder adjacent to the parking lot at penitente canyon. while i never wanted to claim the credit (and the resulting glory) for these fine problems, the recent submission by john "dumpkin-pants" maurer detailing my shithouse bouldering prowess has forced me to "come clean".
many fine problems exist, a few requiring spectacular dynamic opening moves involving running leaps off of small rocks near the boulder. in this regard, these problems are most likely different than those found at shelf road, except in the unlikely circumstance that the rocks surrounding the shelf road outhouse are laid out in the exact configuration as at penitente. if my memory serves me correct, any attempts at problems of this nature at shelf road would be quite painful indeed, requiring leaps off of the numerous clumps of cacti surrounding the boulder. any problems attempted in this manner would be quite "sharp".
any readers who have sampled the fine shithouse problems at penitente canyon are welcome to offer their opinions. don't forget to sample the "the flying dumpkin", just be sure to make the mantle finish so you don't eat it.
