Mount Shuksan (Wikipedia) Mount Shuksan is a glaciated massif in the North Cascades National Park. Shuksan rises in Whatcom County, Washington immediately to the east of Mount Baker, and 11.6 miles (18.7 km) south of the Canada–US border. The mountain’s name Shuksan is derived from the Lummi word [šéqsən], said to mean “high peak”. The highest point on the mountain is a three-sided peak known as Summit Pyramid.
