Mt. Olympus (7,980 ft.), the highest in the Olympics, is one of the most spectacular areas in Washington. Climbing season usually begins in late June and goes through early September. Some of the dangers climbing this peak are: glacier travel, rock fall, and avalanche potential. Climbing parties should be skilled in crevasse self-rescue and should possess other technical skills as required by the chosen climbing route. Climbers face additional risks ascending the true summit's summit block 60 vertical feet high: either 4th-class climbing on dangerous talus or 5th-class rock climbing. Climbers attempting the true summit must know how to protect themselves from falls on rock and ice and from rockfall.
