About this map

Black Hawk anchors this 1942 survey, situated at the confluence of several gulches where mining and mountain topography dictate the local geography. The map captures the transition from the concentrated urban density of the Central City boundary and the industrial footprint of the Summit Mine to the remote ranching and forest lands of the Front Range. Named gulches like Chase Gulch, Russell Gulch, and Fourmile Gulch create a complex drainage network feeding into North Clear Creek and Ralston Creek.

Evidence of early community infrastructure is preserved through the locations of the Mountain House Sch and Bay State Sch, alongside landmarks like Junction Ranch. The terrain is dominated by significant peaks such as Tremont Mtn, Blackhawk Pk, and Douglas Mtn. This document, which includes data from a Denver City special survey, details the winding paths of Golden Gate Canyon Road and Gap Road as they navigate the high-elevation divide between Gilpin and Jefferson Counties.
