1987 Map of Logan

About this map

The Missouri River forms at the confluence of the Gallatin River and other tributaries near the settlement of Trident, a landscape defined by its vital water and rail corridors. This late twentieth-century topographic study captures the industrial and natural geography of Gallatin County, where the Burlington Northern railroad follows the river bends alongside remnants of an Old Railroad Grade. Industrial activity is evident at the Open Pit Mines and various Storage Bins scattered near the tracks, while the local history of Logan is anchored by its Cem and proximity to the Headwaters State Park. The map also illustrates the agricultural and infrastructure network of the era, from the Warm Springs Canal to the presence of a Gaging Station and multiple Trans Lines cutting across the gulches of Big Davis Gulch and Cottonwood Gulch.
