Starts in the bottom, left corner on a juggy ledge. It then traverses up and right past a two finger pocket and some slopey crimps to a decent slopey rail. Then, throw up and left to a top ledge and mantle up. It requires some high feet and is a little sketchy but well worth climbing.
Location
The boulder is the one on the left that you pass on the way down to Monkey Traverse. It is right along the trail and is hard to miss
It's a rather different feel (and harder) if you do it "pure" mantel style compared to reaching up with right hand to the higher, rounded hold while working a semi-mantel with left hand. Good either way (and if doing pure mantel, can use either arm).
