Same approach as to Bitchy Virgin. Bitchy Virgin is the left corner, Unamed starts on the right block of stone. Decent climbing, the corner is definitely enjoyable for a 5.3 leader.
P1: Climb the large block of stone to a ledge. (5.0, 40', PG)
P2: Climb up and right to the pine tree. Move up to the corner until GTLedge. (5.3, 100', PG)
It's probably easiest just to single rope rappel to the ledge and then rappel the last 40'.
It's not the best 5.3 in the Gunks, but it's generally open, quiet and enjoyable climb.
