1971 Map of Coal Bank Draw

About this map

Irene Hills dominate the western landscape of this Wyoming interior, situated across the boundary between Campbell and Converse counties. The drainage network is particularly dense here, with Antelope Creek flowing eastward through the north while the Cheyenne River and its tributary, Dry Fork, cut across the southeastern corner. This early 1970s survey captures the region's ranching and industrial infrastructure, notably the Irwin Ranch and the primary thoroughfare of Irwin Road. Evidence of resource exploration is scattered throughout the drainages, documented by several Drill Hole and Oil Well locations. Water management is visible at the Porcupine Reservoir and various points along Woody Creek and Coal Bank Draw, including a specific Flowing Well that highlights the essential nature of water rights in this arid environment.
