Doesn't the 4th pitch go up the chimney on the other side of that tower (out of sight)? I don't seem to remember it facing west ...

I think George is correct, although when we did it we went around to the left like the photo. The climbing was mostly stemming and pretty easy.

You may be right, but this is the route we climbed (and the one we thought was described in the descriptions we read.) It didn't feel off route to me.

Interesting! I guess there are two ways to do that 4th pitch. We definitely went up the crack around the corner.

I climbed it like in the photo as well (carried on route, thanks). You'll end up there if you stay in the left leaning crack system and don't "traverse back right" like it says to do here in the mp description for the 3rd pitch. It is definitely a "chimney with a overhanging start," but it's not that hard. It puts you right at the base of the black face.
