About this map

The high plains of eastern Colorado are defined by a network of seasonal water bodies and section-line roads along the Cheyenne Co Kiowa Co line. This landscape, characterized by ephemeral drainage basins, features localized landmarks such as Oswald Ranch and several named depressions including Arsenic Lake and Lewis Lake. The drainage of Rush Creek traverses the northern portion of the quadrangle, serving as a primary hydrological feature in an otherwise arid expanse.

A strictly organized grid of county roads, including Co RD 40 and Co RD 37, provides the primary infrastructure for the sparsely settled territory. These routes follow the Public Land Survey System boundaries across townships T16S through T18S. The naming of features like Alkali Lake and East of Lewis Lake reflects the unique soil chemistry and water retention patterns of this prairie environment, offering specific points of reference for land use and local history researchers studying the ranching traditions of the region.
