About this map

The arid landscape of Big Horn, Wyoming, is defined by an intricate network of drainage channels and small-scale water management features in this mid-1960s study. The terrain is dominated by the winding course of Sand Draw and Foster Gulch, which cut through the high prairie. Scattered across this dry topography are several engineered basins, including the namesake Jack Horner Reservoir and the Tommy Tucker Reservoir, illustrating the critical role of water storage in this section of Wyoming.

Subsurface exploration is evident throughout the quadrangle, with numerous entries for Wells, Drill Holes, and a specific central Drill Hole indicating active resource surveying or development during this era. The map provides a detailed view of the section lines and township boundaries of T. 54 N. and T. 55 N., showing how human infrastructure and irrigation efforts like North Snyder Reservoir were fitted into the natural contours of the Big Horn Basin.
