1987 Map of Negro Hollow

About this map

Negro Hollow characterizes this Jefferson County landscape, where the high-altitude terrain is carved by a network of drainage corridors. Surveyed in the late 1980s, the map reveals a remote area dominated by significant topographical shifts, specifically around Cottonwood Canyon and the southern reaches of Timber Canyon. These natural features dictate the passage through the region, with Milligan Canyon Road serving as one of the few established thoroughfares navigating the complex elevation changes. The presence of Rock Spring and an additional unnamed Spring suggests the vital importance of natural water sources in this high Montana environment. This provisional survey captures the intersection of natural landmarks and rural transit routes before modern development, offering a precise view of the geographic formations that have historically shaped local land use.
