The Continental Divide runs prominently through this 1954 survey of Jefferson County, following the high ridges of Rampart Mountain and Sheepshead Mountain. This high-altitude landscape is defined by the headwaters of the Boulder River and Bison Creek, where a network of gulches and creeks—including Kit Carson Gulch and Buffalo Gulch—drains the eastern slopes. The settlement pattern reflects the area's mid-century transit and industrial needs, anchored by the Great Northern and Northern Pacific railroads that parallel the valleys.
