Peshastin Pinnacles, Butterbrickle Route on Martian Tower. The south chimney was climbed in April by J. Brottem and me. The route begins at the south notch, climbs across the slab a few feet, and then up to a belay with bolts in place. Climb into and up the chimney to a ledge, and then up a short face to the summit. Bolts with hangars are in place. About 6 bongs and some medium horizontals were used.
