2014 Map of South of Ana River

About this map

Summer Lake dominates the western half of this landscape, its expansive shoreline defining the transition between the high desert flats and the rising terrain of Lake County. This 2014 survey documents the hydrography of the alkali basin, showing the lake's reach within the Public Land Survey System grids of t31s r17e, t31s r18e, t32s r17e, and t32s r18e. The cartography emphasizes the stark natural divide where the water meets the eastern topography, providing a detailed record of the shoreline and elevation contours as they existed in the early twenty-first century. This specific quadrangle captures the open, undeveloped character of the basin, an essential reference for understanding the hydrological history and land management boundaries of this distinctive Oregon region.
