About this map

Thunder Basin National Grassland dominates this high-plains landscape in Converse County, where the topography is defined by seasonal drainages and wide flats rather than dense settlement. The southern portion of the map is shaped by the Dry Fork Cheyenne River, which receives intermittent flows from tributaries like Alta Cr. The area is characterized by vast open grazing lands and complex land management patterns, indicated by the township and range boundaries such as t39n r72w and t38n r71w.

Remote landmarks provide orientation for researchers of Wyoming's ranching and grassland history. Features like Dilts Flat and the aptly named Calamity Gulch suggest a history of rugged navigation across the prairie. The drainage network, including Lonetree Cr and Bear Cr in the north, illustrates the essential water sources that dictate the movement of livestock and wildlife through this semi-arid environment.
