About this map

Umatilla National Forest occupies this high-elevation landscape along the border of Morrow and Umatilla counties. The drainage network is defined by numerous seasonal and perennial watercourses, including Thompson Cr, which features Thompson Falls and its associated Thompson Falls Spring. The terrain is marked by distinctive topographical landmarks such as Potamus Point, Zion Scope, and the open expanses of Buckaroo Flat and Thompson Flat.

A complex network of Forest Service roads, such as Natl Forest Develop Road 5316 and Natl Forest Develop Road 375 Trl, provides access across the heavily dissected plateaus. These routes connect vital water resources like Matlock Waterhole and W Gopher Pond, which are essential features in this arid timberland. The map provides a detailed view of the land management and hydrology of the Blue Mountains region during the early twenty-first century.
