About this map

The North Platte River carves a critical path through this expansive Wyoming landscape, anchoring the regional hub of Casper and its neighboring communities like Mills and Evansville. By the late 1980s, the area's complex water management system is clearly defined by the massive Pathfinder Reservoir, Seminoe Reservoir, and Alcova Reservoir, which support both agricultural irrigation and recreation at Seminoe State Park. The geography is defined by a series of dramatic uplifts, including the Laramie Mountains, Ferris Mountains, and the Shirley Mountains, which hem in the high-altitude Shirley Basin.

Transportation networks are heavily represented by the Burlington Northern RR and Chicago and North Western RR, alongside major arteries such as Interstate 25 and U.S. 20-26. Outside the urban center, smaller settlements like Bairoil and Jeffrey City serve the mineral-rich interior, while the vast Pathfinder National Wildlife Refuge and Medicine Bow National Forest protect the high-desert and mountain ecosystems. The map also traces intricate county lines across the Great Divide Basin, connecting Natrona, Carbon, and Fremont counties.
