[Redacted]

About 50 feet above the obvious starting corner of

Tres Facile

, above and to the right of

Black Monday

, is a slightly overhanging headwall with two bolted lines. The route described here, called

Gas Chamber

by the FA, is the right-most. Start up

Tres Facile

(5.6 but readily 4th classable) until able to break left to two bolts marking a somewhat contrived line to the base of the overhanging headwall. Puzzle through the strenuous moves above, then cope with the likely pump to the anchors, passing three more bolts en route. The narrative for the route in the Ruckmans' guide has this as 11b/c (although their topo shows it as 11c, a time-honored tactic of guidebook authors reluctant to pin down a grade), but it seemed harder than

Cross Town

and

Mass Wasting

to me.

Above the start for

Tres Facile

.

Draws, but if skittish about soloing a 5.6 move 15-20 feet off the ground, bring some gear. Lower from anchors; one rope is fine.
