Colin Haley on the Cassin Ridge at 17,500' after ascending Denali Diamond.

Descending at 17,000 feet on Denali's west buttress on a calm evening. Visible almost 15,000 feet below are many small tarns and lakes of the north side tundra.

Evening light illuminates Mount Hunter's north face, with distant thunderstorms dissipating over the Susitna Valley.
