At base camp after the 1967 first ascent of the Catenary Ridge. North face of McArthur in background. Back when I still had hair.

Climbing the north ridge of Dak Tower, the first of two peaks to be traversed on the Catenary Ridge of Logan. Tents of Camp I barely visible below. Taken on the first ascent in 1967.

Taken on the first ascent of the Catenary Ridge in 1967. Warren Bleser on the left; Don Schmechel on the right. Wind picking up. Ultimately it became sufficiently strong to keep us from making it to the Main Peak.
