Mount Constance, the Olympic Mountains’ third-highest peak, dominates the eastern range and Seattle’s western skyline while rising with exceptional steepness above the Dosewallips River and standing relatively close to Hood Canal. Its massif includes nearby peaks and ridges around Lake Constance, and its drier northeastern setting leaves it with far less permanent snow and ice than Mount Olympus, apart from the remnant Crystal Glacier. Named in 1853 by George Davidson for Constance Fauntleroy, it was first climbed in 1922. The mountain also saw fatal military plane crashes in 1941 and 1975, and its geology reflects oceanic crust, sedimentary material, and repeated Pleistocene glaciation.
