1969 Map of Brewer Reservoir

About this map

Hay Creek Ranch anchors this high-desert landscape in Jefferson County, where the drainage of Hay Creek flows toward the Brewer Reservoir. The terrain is defined by the steep-walled breaks of Dewies Canyon and Wagonblast Canyon, which cut through the Baldwin Hills in the western half of the quadrangle. This 1969 field-checked survey illustrates a working ranching environment, characterized by isolated infrastructure like storage bins, a Drill Hole, and a borrow pit. Water is the primary driver of settlement here, with numerous sites including Anderson Springs, Mud Creek, and Willow Creek supporting the livestock and agricultural operations. A network of secondary routes and a Jeep Trail connect these remote landmarks, while the Grizzly Road provides more established access across the southern reaches of the territory.
