1985 Map of Eagle Pass

About this map

Eagle Pass serves as a primary geographic marker in this 1985 survey of Park County, Wyoming. The terrain is defined by its drainage patterns and named geological formations, notably the systems of Oregon Coulee and Coal Mine Gulch. These features suggest a landscape shaped by historical resource extraction and the seasonal movement of water through the High Plains. The network of waterways, including North Fork Dry Creek and Dry Creek, alongside the presence of Mud Lake, illustrates the drainage profile of the region's semi-arid environment during the mid-1980s. This USGS provisional map captures the precise topographic contours of the area's plateaus and depressions as they existed before modern developments potentially altered the surface drainage and access routes.
