Trask Mountain, the highest peak in Yamhill County in the northern Oregon Coast Range, was likely named for Elbridge Trask, who settled nearby in 1852. Its geology reflects both ancient sedimentary formations from the Eocene and later basalt and other igneous material, while ongoing uplift above the Cascadia subduction zone continues to shape the range. Heavy annual precipitation supports dense Coast Range forest and wildlife, and the mountain feeds local watersheds draining toward both the Willamette River and the Pacific. It remains practically important as private timberland, the site of a U.S. Geological Survey seismograph station since 1991, and a proposed wind power location.
