I've heard a rumor that someone once aided that roof. There seems to be a crack system going through it.
The pitch getting up to it looked pretty good too. In this weather, under the roof may just be the coolest spot around.
A little to the right of this and down is a steep, white wall, developed by Eric and Blue called Mine Wall. So far, it just has a 5.11 climb, but it seems like easier routes just left of it could be put up.
