The Boulder settlement sits at the edge of a landscape defined by the convergence of mountain drainages and high ridges in Jefferson County. During the mid-1980s, this area served as a transition point between the developed valley and the extensive timberlands of the Deerlodge National Forest. The geography is carved by a complex network of waterways, most notably the Boulder River and the Little Boulder River, which are joined by numerous tributaries including Galena Gulch and Tesky Creek.
