Big Four, Tower Route. This 4000-foot north-side route was completed by Ben Guydelkon and Ron Miller on July 25. From the end of the ice-caves trail, they traversed to the northeast side of the first tower to a prominent gully. Climbing this gully, they were able to work west onto and up the first tower. After rappelling into a notch, the next two towers were climbed. Some more rock climbing led to a long, steep, exposed snowfield and the summit. NCCS IV, F7.
