2020 Map of Northeast Harney Lake

About this map

Harney Lake and the marshy expanses of Mud Lake dominate the southern portion of this high desert landscape in Harney County. This modern survey illustrates a remote corner of the Oregon basin where seasonal water levels dictate the character of the terrain, particularly within the broad, flat basin of Sunset Valley. The map details a network of rural access routes essential for ranching and land management, including the long stretch of Oo Ranch Rd that skirts the northern edges of the wetlands. Other corridors like Weaver Springs Rd and Mccanna Rd provide the primary infrastructure through the interior hills. The mapping reflects the enduring ranching heritage of the region, where roads are named for established families and landmarks like Castle Rd and Raven Rd navigate the sparse, arid elevations above the lake beds.
