~1/3 of the way up the summer route, traverse right across to a long debris field. Early in the season this is a heinous shwack, could become more feasible in big snow years. Follow the debris field up past the base of the large slabs that make up the bulge of rock in the center of the ravine. Cut up a short (~30 ft) and steep (55 degrees) snow section into a short chimney/boulder to top out. Follow ridge out of the ravine.
Aim for the long and thin debris field that forms just left of center on the ravine. Should be a bushwhack most of the way.
Was soloed so definitely can be done without pro, maybe would be comforting when moving through the chimney just for exposures sake.
