Sauk Mountain is a mountain summit located in Skagit County of Washington state. It is situated immediately north of Rockport State Park and the North Cascades Highway, on land managed by the Mount Baker-Snoqualmie National Forest. Sauk Mountain is positioned west of the crest of the North Cascades Range, approximately nine miles east of Concrete, Washington, and 17 miles north of the town of Darrington. Its nearest higher peak is Helen Buttes, to the northeast. A popular two-mile trail provides hikers with good views from the craggy summit of Mount Baker, Mount Shuksan, Mount Chaval, and the Picket Range. The mountain's name Sauk comes from its position immediately north of the confluence of the Sauk River with the Skagit River, which in turn comes from the Sah-kee-ma-hu (Sauk-Suiattle tribe), a group related to the Skagit tribes. Precipitation runoff from Sauk Mountain drains into tributaries of the Skagit River.
