About this map

Pawnee National Grassland dominates the southern portion of this landscape, where the high plains of northern Colorado meet the Wyoming border. The terrain is defined by the dramatic escarpment of the Chalk Bluffs and the flat-topped Simpson Mesa, which guide the drainage of numerous intermittent waterways. These include Simpson Creek to the north and the West Fork Willow Creek to the southeast.

A network of named windmills, such as the North Owl Windmill, McCormick Windmill, and High Five Windmill, underscores the vital importance of groundwater for ranching in this semi-arid region. The map tracks the rural infrastructure of Weld County through a grid of section roads, including CO Road 128 and CO Road 37, which navigate the varying elevations between the bluffs and the open grasslands.
