2014 Map of Pea Ridge

About this map

Pea Ridge rises as the central topographic prominence in this high plains landscape of Phillips County, where a network of seasonal watercourses has carved a complex series of breaks. The drainage system is defined by Fourchette Cr and its various tributaries, including the N Fork Fourchette Cr and S Fork Fourchette Cr. These coulees, such as Horse Pasture Coulee and Clayton Coulee, reflect a long history of rangeland use, where naming conventions often identified specific grazing or management areas. Human intervention in this arid environment is most visible through a series of catchment basins, notably Siwash Reservoir, Shale Reservoir, and the intriguing Fish Fossil Reservoir. This 2014 survey by the U.S. Geological Survey documents the traditional land divisions of the Public Land Survey System, including t23n r29e and t23n r30e, illustrating how the grid of section lines overlays the irregular natural drainages of the Missouri River breaks region.
