About this map

Industrial infrastructure and geologic formations define this high-desert landscape in south-central Wyoming. The town of Sinclair sits at the heart of the sheet, characterized by its massive oil Refinery and Filtration Plant, serving as a critical node along the Union Pacific railroad and the Lincoln Highway. The map captures the complex engineering required to support this desert outpost, including a network of Pipe Lines, the Parco Ditch, and an underground Telephone Cable traversing the scrubland.

Beyond the industrial center, the terrain is shaped by the sweeping curves of the North Platte River to the north and the prominent geological uplift of the Grenville Dome to the south. Local landmarks like Rattlesnake Butte and the Sinclair Airfield provide orientation in the open country, while the Duncan Ranch represents the traditional agricultural footprint. The presence of the CAA Relay Station and a Gaging Station on the river underscores the area's importance for regional transportation and resource management during the mid-20th century.
