The Mark O. Hatfield Memorial Trail is a proposed long-distance trail through the Columbia River Gorge in Multnomah County and Hood River County, Oregon. The trail will be approximately 60 miles (96.6 kilometers), although the trail is still unofficial and its exact course is yet to be determined. The trail was first proposed by Tom Kloster on June 20, 2010 and suggests the Mark O. Hatfield Memorial Trail use existing trails from Multnomah Falls to Starvation Creek. Prior to this suggestion, the Talapus Trail, connecting the Pacific Crest Trail and Larch Mountain was slated for construction in 1974. Hikers openly used trails in the Bull Run into the 1980s, including the Talapus Trail (never officially constructed).
