1972 Map of Otis SE

About this map

The Washington Co and Yuma Co boundary line bisects this 1970s landscape, revealing a vast high-plains terrain defined by subterranean water access. The map's most striking characteristic is the sheer density of groundwater infrastructure, with dozens of Well labels dotting the landscape across nearly every section of the grid. This pattern reflects the region's total dependence on irrigation and agricultural pumping in a semi-arid environment. Human industry is concentrated at a single Gravel Pit near the county line, while the remainder of the quadrangle is largely open, divided by a precise network of section lines and range boundaries. This survey provides a primary record of the rural land-use patterns and hydrological development in eastern Colorado during the early 1970s.
