2023 Map of Ancient Lake Well

About this map

High desert terrain dominates the landscape along the border of Harney Co and Malheur Co in southeastern Oregon. This portion of the Great Basin is defined by the prominent Grassy Ridge, where subtle elevation changes and dry watercourses mark a largely undeveloped expanse of public land. The mapping provided by the U.S. Geological Survey and Bureau of Land Management reveals a network of primitive roads and section lines across the high-elevation flats. The scarcity of named landmarks underscores the isolation of this region, where the Public Land Survey System grid provides the primary framework for navigating the desert floor between distant outposts and ranching tracks.
