Silverthrone and Mather. On August 11 Vern Tejas, John Dargis, Wally Orr, Terry Pearce, my wife Roni and I climbed Silverthrone by the Washburn route. Beautiful weather and views of Mather convinced us to do Mather as well. While Roni and Pearce, recouped in Base Camp, Tejas, Dargis, Orr and I climbed the west ridge of Mather for a second ascent. The climb consisted of a long ice face up to 55° and some beautiful ridge walking, followed by 500 feet of exciting traverse under a knife-edged ridge and finally some great ridge bashing as we chopped the ridge down to reasonable width.
