Last weekend I did the East Buttress of Lower Cathedral with Evan Bigall. Felt pretty good about leading the 5.10c pitch onsight. We also tried to work on a new route on Middle Cathedral, between The Turret and the upper North Buttress. The first pitch (off Tree Ledge) was a dirt festival, and then had some loose flakes (I didn't touch 'em, but Evan did while following and one of 'em tumbled off). On the second pitch, Evan knocked off a big loose flake on the lead. It started to go, but he held it on with his head (he was on free moves), until I could gather up the ropes and hide under an overhang. We survived it. The first pitch is not worth repeating, but there might be an alternative (wider crack) pitch to its left.
