Really enjoyed this one - Ken, Chris, and I parked right beneath Webb Mountain's west slopes. We set off across the flat desert towards distant-looking Signal Mountain. The closer we got, the more colorful and varied the terrain got. We left the main wash east of the peak and headed for what looked like a solid ramp, heading right to the main summit block. We were disheartened to find two gashes along this east ridge that required some downclimbing and re-ascending. Eventually, we got to a spectacular saddle right beneath Signal. A large fin, made of volcanic rhyolite, emanated from the cliffy summit block right towards us. We skirted its left (south) side, traversed to the south ridge of Signal, and climbed this steep, and blocky ridge straight to the top. Loose rock abounds! We were greeted to a lonesome, unobstructed vista. Very cool area, very remote.
