1998 Map of Boise City SW

About this map

The Rita Blanca National Grassland dominates this landscape along the border between Oklahoma and Texas. This 1998 revision of a 1969 topographic study reveals the high plains character of Cimarron and Dallam counties during the late twentieth century. Water is the primary driver of the settlement pattern here, with numerous wells and intermittent drainages like Aqua Fria Creek etched into the terrain. The northern reaches of the map are defined by the wide corridor of the Beaver River, which provides a topographical contrast to the more uniform sections of the grassland to the south.
