About this map

Salish Mountains topography dominates this 2017 survey of Lake County, Montana. The landscape is defined by the prominent peak of Irvine Hill and the sprawling drainage systems of Garcon Gulch and Oliver Gulch. These valleys channel water into perennial streams such as Irvine Cr and White Earth Cr, which move across the lower-elevation Irvine Flats in the eastern portion of the quadrangle.

Local infrastructure is represented by a network of rural routes that skirt the steep terrain, including Garceau Gulch Rd and Irvine Flats Rd. The map illustrates the transition from the high, wooded peaks of the Salish range to the open flats below. Researchers will find a detailed look at the Public Land Survey System, showing the township and range lines that divide this portion of the Montana landscape.
