2020 Map of South of Ana River

About this map

Summer Lake dominates the western portion of this high desert landscape in Lake County, defining the hydrology and terrain of the basin. The survey highlights the expansive alkali shoreline and the complex drainage patterns feeding into the lake bed. While the interior remains largely undeveloped, the map is structured by the Public Land Survey System, specifically within the townships of t31s r17e, t31s r18e, t32s r17e, and t32s r18e. This 2020 edition provides a modern topographic baseline for the region, capturing the subtle elevation changes across the open flats and the rimrock edges of the Ana River basin to the north.
