This route is not really part of the Ironsides. I don't know what the rock is called. Chump and a couple other routes exist across the valley from the Ironsides. There is a cool cave that allows passage to the other side. On the other side of the cave there are two overhanging routes to the left. Chump is the short line on the left. This is a cold place!!!
Fun pumpy moves pull out through an overhanging bulge to a small ledge and the anchors. The rock isn't the best, but the moves are fun. A good warm up for Pump. A couple other OK routes lie around the corner on the other side of the cave.
3 or 4 bolts.
