McKenzie Flat defines the high plateau of Natrona County, showing the sparse water resources and expansive cattle country typical of this part of Wyoming. In the early 21st century, this land remains largely undeveloped, characterized by seasonal drainage patterns and isolated water sources like Sand Springs and Mud Spring. The terrain is shaped by the long descent of McKenzie Draw, which cuts through the central landscape. Modern access is limited to a few arterial routes such as E Ormsby Rd, reflecting the enduring rural character of the region. This survey captures the intersection of traditional rangeland with modern topographic precision, detailing the subtle elevation changes that govern water flow across the flat.
