About this map

Umatilla National Forest defines the character of this high-plateau landscape along the boundary of Morrow and Umatilla Counties. In the late 1960s, this area served as a functional working forest and recreational landscape, evidenced by the network of pack and jeep trails such as the Section (Pack) and Line (Jeep) Trail. Water resources were critical to the livestock and forest management of the era, marked by features like Thompson Flat Well, Matlock Waterhole, and Divide Well.

Isolated outposts like Florence Cabin, Thompson Corral, and Juniper Camp highlight the seasonal and remote nature of human activity in these woods. The terrain drops sharply from the level expanse of Thompson Flat and Buckaroo Flat into deep drainages carved by Potamus Creek and Matlock Creek. Notable natural landmarks include the Thompson Falls and the dramatic overlook at Potamus Point, while the presence of a Borrow Pit suggests the ongoing maintenance of the forest's primitive road system.
