About this map

The confluence of the Madison River and the Jefferson River defines this Gallatin County landscape, marking the headwaters region as it appeared in the early 21st century. The city of Three Forks serves as the primary hub, showing a grid of residential streets south of the major Interstate 90 corridor. North of the highway, the terrain rises into the rolling hills of the Copper City and Wheatland areas, where a network of modern residential loops like Horizon Loop and Aurora Loop meet older thoroughfares such as Old Town Rd.

Water management is central to the local economy, evidenced by the extensive network of irrigation features including the Lower Jefferson Ditch, Darlington Ditch, and Francis Walbert Ditch. Local transit and infrastructure are well-documented, from the Jefferson River Bridge to the small-craft facilities at Three Forks Airport and Hasskamp Airport. Genealogists will find the Headwaters Cem situated near the river bend, providing a specific point of interest for local family history research.
