to the west, Mount Constance has little in the way of glaciers and permanent snow because the eastern, and particularly this northeastern, portion of the Olympics receives far less precipitation. However the narrow and steep Crystal Glacier still exists on the mountain's north face, shaded by the bulk of the main peak and with a small lake at its terminus. In addition, the treeline is higher here than mountains to the west, also hinting at the drier alpine conditions. By virtue of its position at the eastern edge of the Olympics, Mount Constance also enjoys spectacular vertical relief. For example, it rises over above the Dosewallips River to the south in only 3 horizontal miles (5 km). It is also only from the tidewater of

History

In 1853, surveyor George Davidson named three mountains in the Olympics. He named Mount Ellinor for Ellinor Fauntleroy, who later became his wife, Mount Constance for Ellinor's older sister and The Brothers for her two brothers. A U.S. Army bomber plane from

crashed below the peak of Mount Constance in September 1941, killing all six aboard. 21 March 1975: an air traffic controller confused aircraft call signs and cleared a McChord AFB based C-141A, 64-0641, of the 62d Military Airlift Wing, to descend below safe minimums and it impacted Mount Constance in the Olympic National Forest, Washington, killing 16 passengers and crew

During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer. The months July through September offer the most favorable weather for viewing or climbing this peak.

Climbing

Routes on the mountain are from Class 3 to mid-Class 5, with ratings from Grade 2 to Grade 4. Mount Constance was first climbed in 1922 by R. Schellin and A.E. Smith from the southeast.
