1973 Map of Last Chance NW

About this map

Middlemist Creek and Beaver Creek define the drainage patterns across this High Plains landscape, where the borders of Adams, Washington, and Arapahoe Counties converge. The terrain is characterized by the broad Cottonwood Valley and numerous seasonal draws including Bobcat Canyon and Rattlesnake Creek. Settlement is sparse, represented by Prairie Farms and isolated infrastructure like the Landing Strip in the southeastern quadrant. This survey, conducted shortly after the 1972 aerial photography phase, captures the region's agricultural and ranching character through its network of fence lines and unimproved roads. Notable landmarks such as a Picnic Area and a remote Substa indicate the limited but essential human footprints across these expansive grasslands during the mid-1970s.
