2020 Map of Selle Gap

About this map

The Harney and Malheur county line bisects this high desert landscape, dominated by a complex network of water management features essential for life in the arid Oregon interior. The northern reaches of the Warm Springs Reservoir occupy the southwest corner, while the interior is dotted with a series of smaller impoundments and named water sources like Williams Charco and the Selle Gap Reservoir. The terrain is defined by basaltic features and deep gulches, most notably Selle Gap and its smaller counterpart, Little Selle Gap. High points such as Black Butte and Twin Knolls provide orientation across the sagebrush-covered flats. The presence of numerous developed springs, including Shovel Spring, Mud Spring, and Trail Spring, highlights the historical and ongoing importance of reliable water for livestock and local land use. Transport through this territory relies on the north-south corridor of Juntura-Riverside Rd, which connects these remote basins.
