If you are looking for a new project at Flag, this might be your ticket.This rarely repeated problem involves climbing a complete loop around the Beer Barrel boulder. Start on the underclings on the south east side and traverse clockwise, finishing on a hard crux on the north east side. It's helpful to have someone block for you as you pass the crowds on the other problems.
P.S. If anyone knows the official name, first ascentionist or has any other background information on this problem, please share with the rest of us.
I can make out the entire traverse except for the ending, do you end by doing the v6 'North West Corner' problem or do you stay lower, or do you top out after finishing the West Face Traverse?
After the west-side traverse, continue around the corner (tricky) and top out on the north-east side (listed as the NW corner on this site) of the boulder with several tenuous slopes and a heal. The loop is more like V8 or V9.
