This route can probably be done in one pitch, but there would be too much rope drag. The first pitch is a low grade friction slap to some chains, then its up into a wide off width chimney with 3 bolts. The chains are at the top of the chimney, or you can scramble up a bit further to another set of chains that can be rapeled off.
The obvious large crack that runs up the southwest corner of the Big Rock
5 bolts on the bottom section with rapel rings and an anchor station. 3 bolts in the chimney with your choice of chains on the chimney section.
