1952 Map of Ervay Basin SW

About this map

The Rattlesnake Hills and Black Mountain dominate this landscape within Natrona County, where early-to-mid 20th-century ranching and transit infrastructure shaped the high desert terrain. The presence of the Holiday Homestead (Aband) and the Asbell Homestead Site reflects the legacy of individual land claims in the Beaver Divide region. Historic transportation routes are well-defined, including the Poison Spider Road and the Freight Road, which likely supported livestock movement and logistics between isolated outposts like the Strawbaker Corral. Water management, critical for survival in this environment, is evidenced by Boyle Reservoir and numerous named water sources such as McKenzie Spring and Little Cross L Spring. A Landing Strip and a Pipeline represent the gradual integration of modern industrial and aviation facilities into the remote basin during the post-war era.
