Climbing and access information for this peak is on Page 310 of the book.
In addition to the route described in the book, you can climb Buckhorn Peak via its broad West Ridge from Uncle Ike Creek. Leave the creek at an elevation of roughly 7,000 feet. There are some cliffs on this big ridge but they are easily skirted. USGS Fallert Springs
