1969 Map of Chimney Butte

About this map

Industrial expansion and resource extraction define this 1969 landscape in Sublette County, where an extensive Oil Field is marked by a network of Gas Wells, Oil Wells, and numerous Drill Holes. The rugged topography is anchored by Chimney Butte, with water management appearing through the Chimney Butte Reservoir and Flat Top Reservoir to support the local operations. Transportation in this high-desert environment relies on the Calpet Road and Big Piney Calpet Road, which traverse the complex terrain of the Dry Basin. The map captures a moment of significant geological exploration, including the Chimney Butte Pit No 3 and a network of underground infrastructure indicated by a prominent Pipeline. These features reflect the mid-century energy boom that transformed this portion of the Wyoming basins.
