On July 24th, Liam Wylie and I climbed Open Book, a six pitch, 450 foot, grade III rock route on the southeast face of Grunt Arete, the first rock feature east of Disappointment Peak's SE Ridge, beginning in Garnet Canyon. Open Book is a Teton classic by all standards, with a stacked deck of unrelenting 5.8+ to 5.10- climbing above dramatic exposure. We finished the route in about eleven hours car to car, and had a tremendous time doing so.
