On Saturday June 24th Bobbi Clemmer and I got benighted on a wild ascent of a wet Trinity Buttress (a.k.a. Symmetry Crag 4). Originally graded 5.9 by Yvon Chouinard and T.M. Herbert in 1970, the climb ascends two-thirds of the major rock buttress west of the popular Guide's Wall with a few stellar, and a few not so stellar, pitches.
