Cathedral Rock in the Bighorn Crags is one of Idaho’s most unique and impressive peaks. There are only technical routes to its tiny summit. Surprisingly, few climbers have tested its vertical walls. This is due, in part, to its remote location. I climbed this peak with Dana Hansen in 1984 via a one-pitch gully that separates the peak’s two summit blocks. We found a piton and webbing documenting a previous ascent but no summit register. It is unlikely that this peak has been climbed more than a handful of times since then. The peak’s rock is good, clean granite and there are lots of potential climbing lines waiting for first ascents. USGS Mount McGuire
