About this map

The high-elevation mining camp of Kirwin serves as a focal point for this early twentieth-century survey of the Absaroka Mountains. Situated at the headwaters of the Wood River, the area is defined by sharp peaks like the Washakie Needles and Mt Crosby. Mining activity is physically documented through landmarks such as the Gold Reef Tunnel, while the region's timber resources are indicated by Dicks Sawmill and several unnamed mills.

A network of isolated ranching outposts, including Antler Ranch, Browns Ranch, and the Double Diamond Ranch, establishes the settlement pattern along the valley floors. The map also delineates the complex drainage systems of the Wind River and Grey Bull River, alongside the jagged administrative limits of the Yellowstone Forest Reserve. Geologic features like Galena Ridge and Meadow Creek Basin reflect the prospecting environment of the era before more modern developments reached this part of the Bighorn and Fremont County border.
