Interstice

This is an interesting route up the face between Birdie Party and Mother's Day Party, on the Mac Wall.

Pitch 1, 80', 5.10b PG: Start below the left end of a small overhang 20' right of Birdie Party and about 10' left of MF. Climb up to the small overhang, place cams in the horizontal, and crank up to the thin seam that goes up from the left end of the overhang. A marginal nut placement can be had before climbing up to the ledge. Head up to the obvious, arching, left facing corner and place several pieces of gear as high as you can before pulling up above it to your next gear at a horizontal crack below a small overhang. Work right across moderate terrain underneath the huge left-facing flake. Place a large cam (blue camalot) before moving right to the MF bolts.

Pitch 2,100', 10d (5.9R), description courtesy of ?? : From the bolted belay, traverse left a bit past the left end of the Birdie Party roof. Look for a thin seam creasing the ceiling: cross the roof at that point (crux). Move up series of shallow corners for 15 or 20 feet, then angle up and slightly left to the GT ledge. 100 feet, 5.10d, PG. Strenuous, a bit continuous, and fun.

The Mac Wall access trail, a 5 minute walk from the Uberfall, leads to the base of MF. Interstice starts about 10' to the left of MF.
