Ruby Mountain is a prominent 7,412-foot (2,259-metre) mountain summit located in the North Cascades Range of Washington state. It is situated in Ross Lake National Recreation Area which is part of the North Cascades National Park Complex. The Diablo Lake Overlook along the North Cascades Highway is at the foot of the mountain. The nearest higher peak is Colonial Peak, 4.2 miles (6.8 km) to the southwest.[1] Precipitation runoff on the east side of the mountain drains to Ross Lake via Ruby Creek, whereas the west side of the mountain drains to Diablo Lake via Thunder Creek. Topographic relief is significant as the summit rises 6,200 feet (1,900 meters) above Diablo Lake in approximately two miles.
