2020 Map of Logan

About this map

The Missouri River forms at the convergence of vital waterways in this Montana landscape, where the Gallatin River flows into the primary channel near the settlement of Trident. This 2020 map documents the transition between the valley floors and the complex drainage systems of the surrounding hills, including Cottonwood Gulch and Big Davis Gulch. Transportation history is embedded in the terrain, marked by the Northern Pacific Railroad Bridge and the critical crossings of the Trident Bridge and Logan Bridge. Small settlements like Logan, Eustis, and Carpenter are positioned along these corridors, serving as focal points for local history. Genealogists can identify specific burial sites at Headwaters Cem and Logan Cem, while natural features like Cress Springs and Spring Cr highlight the hydrology that once dictated the placement of these early western outposts.
