Foster Coulee cuts through this high desert plateau in Douglas County, defining a landscape marked by dramatic elevation changes and essential water management. Water is a central theme of this 2023 survey, which documents infrastructure such as Perry Dam Number One and Perry Dam Number Two alongside natural features like Buck Lake, Clear Lake, and Elbow Lake. The land is segmented by a grid of rural roads, including Leahy Rd S and Rogers Rd NE, which provide access to the remote sections of T28N and T29N. A prominent landmark, Tower Rock, stands as a navigational waypoint in the western portion of the quadrangle. The map reveals the intricate drainage patterns of East Foster Creek as it winds through the coulee, illustrating the relationship between the arid terrain and the water systems that sustain it.
