2020 Map of Louisville

About this map

Louisville and Clasoil anchor the landscape of this contemporary survey, situated where the high plains meet the eastern foothills of the Rockies. The map documents a complex border region where Jefferson, Broadwater, and Lewis and Clark counties converge near the Spokane Hills. To the south, the terrain rises sharply into the Helena National Forest, dominated by peaks like Little Butte and the winding drainages of Sheep Creek and Deep Creek. This area illustrates the modern interface between rural residential development and public forest lands, with a dense network of roads such as Spokane Ranch Road and Canyon Ferry Road providing access to the higher elevations. Genealogists may find particular interest in the Turner Cemetery, located near the headwaters of Spokane Creek, a vital landmark for tracing the history of local ranching and early settlement families in this part of Montana.
