Umatilla National Forest and Wallowa-Whitman National Forest converge on this high-country landscape, where the ridge systems of the Blue Mountains define the human and natural geography. The 1964 field data reveals a working forest infrastructure centered around sites like the Summit Guard Station and established forest camps such as Camp One and Camp Three. The terrain is characterized by a dense network of water sources, including the historically named Sacajawea Spring and Tie Camp Spring, which supported the early logging and grazing operations of Union and Umatilla counties.
