North America, Mexico, Baja California, Gran Trono Blanco

Gran Trono Blanco. The Libro Abierto route on the north face follows a continuous right-facing dihedral for six pitches. There was a little aid on the first three pitches, but these went largely free. The steep route is delightful, mostly cracks and jam chimneys. Except for part of the third pitch, the rock is very solid. The dihedral is just west of two routes done in 1974. It was climbed on March 24 by Alan Bartlett, Mike Graber and me. NCCS IV, F9, A2.
