Oregon National Forest

The Oregon National Forest was established by the U.S. Forest Service in Oregon on July 1, 1908 with 1,787,280 acres (7,232.9 km²) from the northern part of the Cascade National Forest and all of Bull Run National Forest. It extended from the Columbia River to the South Fork of the Santiam River until 1911 when the Santiam National Forest was proclaimed and the southern border of the Oregon National Forest was moved north to the divide between the Santiam River and Clackamas River. On January 21, 1924 the forest was renamed Mount Hood National Forest.
