Mount Ross is a 6,052 ft summit in the North Cascades Range of Washington, United States. It is located within North Cascades National Park and Stephen Mather Wilderness. It rises steeply from the North Cascades Highway and Newhalem, Washington which are both set at the southern foot of the mountain. Like many North Cascades peaks, Mount Ross is more notable for its large, steep rise above local terrain than for its absolute elevation. Mount Ross honors James Delmage Ross (1872-1939), the superintendent of the Skagit River Hydroelectric Project. Ross Dam and Ross Lake also bear his name. Mount Ross was first climbed on August 17, 1969 by Jack Roper, Maurine Roper, and Jan Bergerson. The nearest higher peak is The Roost, to the north. Precipitation runoff from the mountain drains into the Skagit River.
