Oregon Historic Trails Advisory Council
The Oregon Historic Trails Advisory Council is an agency of the U.S. state of Oregon that oversees and provides advice on Oregon's sixteen historic trails, which include trails used in the 19th century by explorers and pioneer emigrants to the region as well as trails associated with the original Native American inhabitants. The council, a division of the Oregon State Parks and Recreation Department, was created by the executive order of Governor Kitzhaber in 1998 and consists of nine volunteer members.
