About this map

The Boulder River winds through the heart of this Jefferson County landscape, serving as the primary drainage for a terrain defined by steep ridges and narrow drainages. To the west, the boundary of the Deerlodge National Forest encompasses high points like Sheep Rock and the South Black Canyon Fork of Cottonwood Creek. The map documents a sparsely populated but working landscape, where small-scale extractive activity is noted at Prospects and a Quarry near the riverbanks.

Prominent landforms like Doherty Mountain and Red Hill anchor the eastern and central portions of the sheet, while named water sources such as Mc Kanna Spring provide critical landmarks in the arid high country. The complex network of canyons, including Cottonwood Canyon and the evocatively named Negro Hollow, illustrates the natural barriers that shaped local transport and land use during the late 20th century.
