2020 Map of Runyan Bench

About this map

Runyan Bench and T U Bench dominate this high-plains landscape in Blaine County, where the terrain is defined by a series of dramatic coulees and creek drainages. The area is characterized by its hydraulic patterns, with ephemeral waterways like Gap Cr and Hedges Cr carving through the breaks. Human adaptation to this arid environment is visible in the placement of Four O'Clock Reservoir and Als Coulee Reservoir, which serve as critical water collection points for local ranching operations. The road network remains sparse, centered on gravel routes like Birdtail Rd and Three Mile Rd that follow the natural contours of the land. This survey illustrates the isolation of these northern reaches, where large-scale geological features like Bullwhacker Coulee remain the primary landmarks for navigation.
