Entering the lieback crux of Tunnel Vision on P3. The chimney below constricts to the point that you're forced out onto the face. You then (one option) need to lieback off of a nice edge inside the groove (~2 moves) to gain some edges where you can stem the rest of the way up. The pro is reasonable but not "bomber" (nut and micro-cam behind hollow-sounding flakes; last solid piece is a #5 Friend 15 feet below inside the chimney, March 15, 2004).
