1986 Map of South of Ana River

About this map

Summer Lake dominates this mid-1980s landscape, occupying a vast portion of the northwestern terrain. The map details the transition from the expansive water body to the complex topography of the high desert along the eastern shore. Grounded in a 1981 field check, the survey documents the intricate network of township and range lines, such as t31s t32s and r17e r18e, which provide the legal framework for this remote corner of Lake County. This provisional edition is particularly valuable for its recording of unimproved roads and trails that traverse the rising slopes east of the lake, offering a precise view of the rural infrastructure before modern developments. The interplay between the flat basin of the lake and the neighboring ridges is rendered with a five-foot contour interval, providing exceptional clarity for those studying the hydrology and land use of the region during this era.
