1978 Map of Trimble Lake

About this map

Mustang Creek winds across this section of the Colorado high plains, defining a landscape shaped by intermittent water and wide-open rangeland. The 1978 survey reveals a terrain marked by natural drainage features like the North Fork and South Fork, which converge as they move through the quadrangle. In an area where permanent water is scarce, Trimble Lake and scattered Well sites serve as critical landmarks for local ranching operations. The presence of Sand Arroyo in the southern portion of the sheet highlights the ephemeral nature of the local hydrology, where dry beds only flow during significant weather events. This map captures the region's character as a sparsely populated agricultural expanse, where section lines and section fences dictate the human footprint over the natural prairie.
