Service Description: Boundaries of Indian Reservations and Trust Lands recognized by the U.S. Bureau of Indian Affairs. The Yakama Nation Mt. Adams Recreation Area is a unique area of the Yakama Reservation. It is the only area within the Yakama Reservation forested boundary that is open to non-Yakama tribal members. Ownership of this area has been in dispute dating back to the Treaty of 1855. An 1890 survey of the Yakama Reservation, accepted by the General Land Office, did not include the Tract-D area. The original treaty map, which included the Tract-D area, was found in 1930 after being misplaced for decades. In the meantime 98,000 acres of the Glenwood Valley had passed into private ownership. Another 21,000 acres were part of the Gifford Pinchot National Forest administered by the Department of Agriculture. After more than 100 years of dispute, in 1972 President Nixon by Executive Order 11670 authorized the return of the 21,000 acre portion of Mt. Adams, including the Summit, to the Yakama Nation. The reservation boundary shown in this data set does not include the 98,000 acres in the Glenwood Valley.
