About this map

Pishkun Reservoir dominates the central landscape of this Teton County survey, serving as a focal point for the regional irrigation infrastructure during the late twentieth century. The map illustrates the complex water management systems of the era, notably the Sun River Slope Canal which winds through the varied topography to the south and east of the reservoir. This engineered waterway represents a significant modification of the arid environment, redirecting vital resources across the drainage basins of Deep Creek and Quigley Coulee.

The terrain is further defined by a series of erosion-carved features including Wolf Coulee and Hay Coulee, which cut across the high plains. Human industry is represented by a Gravel Pit located north of the reservoir, while a network of unimproved roads and trails provides a window into the land use patterns of the 1980s. The transition between township T 23 N and T 22 N is clearly marked, offering a precise reference for those researching local land tracts and historical boundaries.
