1961 Map of Casper

The southern horizon is dominated by the steep ascent of Casper Mountain, where the terrain rises sharply toward Rotary Park and the Garden Creek Waterfall. In the lowlands, the infrastructure of the 1960s economy is evident in the sprawling Oil Tank Farm, the Refinery, and the dual rail lines of the Chicago and North Western and Chicago Burlington and Quincy. Outlying residential developments such as Thorndale Acres and Allendale illustrate the city's post-war expansion south of the river.
