About this map

Mta Fort Wm Henry Harrison dominates the northeastern corner of this landscape, marking a significant military presence just west of the Montana state capital. The terrain is defined by the high elevations of the Helena National Forest, where peaks like Black Mtn and Colorado Mtn overlook a complex network of drainage basins. Small-scale aviation infrastructure, including the Ten Mile Airport and Duncan Airport, is situated along the valley floor near Tenmile Creek, illustrating how the local geography dictates transportation and land use in this mountain environment.

A legacy of mining and homesteading is etched into the names of numerous ravines, such as Nelson Gulch, Colorado Gulch, and Lazyman Gulch. These features, along with the Black Hall Meadows, indicate a history of local resource extraction and seasonal grazing. The map also delineates the boundary between Lewis and Clark County and Jefferson County, showing how political lines follow the drainage divides of the North Fork Travis Creek area.
