This rock is the one you are thinking of when you think of bouldering at Sanitas. It is the first major rock you come to when you take the trail up the hill, marked by a big pine tree right in the middle of the boulder.
Problems here are fun, but not too hard, with a couple of interesting easy highballs and a genuinely fun and long V2 traverse with lots of V0 moves and probably only one spot of V1/V2 trickiness.
This is a pretty nice spot to take a beginner, but if you lap the traverse enough times, you can still get some good exercise. It is close to other worthwhile boulders as well.
Walk up the Sanitas trail, veering left when possible to reach the boulders up the hill.Look for a climbing access sign when you get near the top of the hill and then as you look up and right you will see a chalked-up boulder with a big pine tree right in the middle of it.
Mountain Project's determination of some of the classic, most popular, highest rated routes for North Shelf Block:
This problem starts on the far left side of the North Shelf and traverses right for about 60 feet. V2 is the ostensible rating given in Benningfield's book, which is probably generous, but is reasonable if you get to the last finishing moves. The problem starts with a V1 sequence on good edges with bad feet, and then eases up as you pass the tree. Depending on how contrived you make it, the next 25 feet can either be a virtual walk, or more like V0 - keep your feet off the big ledges if you wa...[more]Browse More Classics in CO
I learned how to climb on Sanitas 15 years ago .The place taught me a lot and proved it could be more difficult w/ a good eye for variations.Such as; the west face of corner rock , check out some crimpy dynos up tp v2.The right side of classy wall ,start w/ a sit down on the arete move up then back down to the start of the dyno,dyno to finish(v2)I put that up in '92 "Circle of Power". The upper boulder has a great low traverse(left to right) that finshes high 15 feet into it on a poor reach to A one finger pocket(v2,Life of Brian , FA Biggwave in '95. Enjoy!
I love how people do a route or problem that has no chalk on it, and then go and claim a first ascent. Do you honestly believe that these problems that you are claiming as first ascents, were never done before?... in 1992 and '95 at Sanitas of all places?!
