Facing the Hobo Cave from the main NWB trail, walk through the cave towards the stream, and the boulder is the last one on the right before getting to the water. Alternatively, this boulder is directly behind the top out for the "Dirty Mike" problems.
Start with right hand on the slopey sidepull and left hand on the same part of the boulder to tue right on a good flat edge. Left heel below the left hand allows for the easy establish. The actual climb is all jugs up the face of the boulder.
Enjoy the photogenic view after the top out!
