1972 Map of Chalk Bluffs East

USGS Topo · Published 1974

About this map

Chalk Bluffs dominate this Colorado landscape, where the high plains of Weld County meet an intricate system of drainages and escarpments. The area is defined by a series of intermittent waterways, including Little Simpson Creek and Simpson Creek to the north, while Geary Creek and its North Fork carve through the central bluffs. This 1970s survey captures a sparse ranching environment, with Eagle Rock Ranch and the nearby Eagle Rock Res serving as primary points of human activity. The terrain is marked by distinctive geological features such as Squaw Rock, standing near a Pipeline that cuts across the western portion of the quadrangle. A network of springs and wells, including Willow Creek in the south, indicates the critical role of water management in this arid stretch of the western frontier.
