The Wolf Fork is a 16.1-mile (25.9 km) long[3] headwater stream of the Touchet River in Columbia County, Washington. Draining off the northern Blue Mountains from in between 5,682-foot (1,732 m) Griffin Peak and Ski Bluewood, it flows north through a narrow valley along the eastern side of Newby Mountain.[2] At the small cabin community of Mountain Home Park, it is joined from the left by Robinson Fork.[4] It continues north to join the North Fork Touchet River, which joins with the South Fork Touchet River another 5 miles (8.0 km) downstream to form the Touchet River near Dayton.[5]
