About this map

The Umatilla National Forest dominates this section of the Oregon high country, where the landscape is defined by steep ridges and deep drainage systems. Central to this area is Turner Mtn, surrounded by prominent geologic landmarks such as Eagle Rock and the high plateaus of Sunflower Flat. The terrain is deeply incised by Big Wall Creek and its tributaries, reflecting a complex hydraulic network that has shaped the regional geography.

Evidence of early livestock and forest management is visible through the concentration of named water sources like Big Willow Spring and Kingbolt Spring. This region, split by the Morrow and Grant County line, was navigated via the Willow Springs Trl and Wilson Creek Trl. The map documents a landscape of named ridges and canyons, including Morphine Ridge and Lost Canyon, highlighting the specific local identifiers used by rangers and early settlers to navigate this portion of the Blue Mountains.
