Mount Constance is a peak in the Olympic Mountains of Washington and the third highest in the range. It is the most visually prominent peak on Seattle's western skyline. Despite being almost as tall as the ice-clad Mount Olympus to the west, Mount Constance has little in the way of glaciers and permanent snow due to the fact that the eastern, and particularly the northeastern, portion of the Olympics receives far less precipitation. In addition, the treeline here is higher than points to the west, also hinting at the drier conditions here.
By virtue of its position at the eastern edge of the Olympics, Mount Constance also enjoys spectacular vertical relief. For example, it rises over 6,900 feet (2,100 m) above the Dosewallips River to the south in only 3 horizontal miles (5 km). It is also only 12 miles (20 km) from the tidewater of Hood Canal. The summit of Mount Constance lies on the boundary between Olympic National Park and Buckhorn Wilderness. The Constance massif includes Mount Constance, Inner Constance and the twin peaks of Warrior and Warrior's Arm.
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.
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.
Boulder Ridge (including the Gargoyles, Charlia Lakes, Cloudy Peak, Alphabet Ridge, and Warrior) and Home Lake / Constance Pass are readily accessed via the Buckhorn Wilderness Area (U.S. Forest Service) side of the Upper Dungeness River Trail and Marmot Pass. An alternative approach to the Mount Constance massif—including Inner Constance and the twin peaks of Warrior—is via the Dosewallips River Trailhead off of US 101 and Hood Canal. A third alternative is to access the Constance massif via Quilcene logging roads (FS 2700 aka "Penny Creek Road" off U.S. 101) leading to a brief 6 to 7 miles (10 to 11 km) ascent to Tunnel Creek Ridge and the high alpine shores of Harrison Lake. In fact, the most stunning views of the east side of Mount Constance and Warrior are readily available from these roads (the lower portions of which are paved) which actually connect to FS 2800 and the Dungeness / Sequim area via the 5000-foot Bon Jon Pass.
