Description
Thin Slice is one of the best 5.10a trad climbs at the City. It is found on the north east side of Parking Lot rock, just east of Cario (5.11a).
The climb starts in a right facing dihedral, and follows a juggy crack with good gear. A small bulge is pulled and the crux finger crack is just above. Figure out the tricky moves along a finger crack and you will arrive at a ledge with 2 bolts. An extra finger sized cam (#1 friend) will be helpful in the upper finger crack.
