The guidebook shows 3 one pitch routes on the east face, right of WOEML. A 10c/d unnamed, Freaky Deaky 5.11+, and Now you see it, now you don't 10+. There is a newish route to the top, where you mention, but I don't have any info about it. I have seen bolted anchors up there, and there's some rap slings on top.
