1987 Map of Sappington

About this map

The Jefferson River meanders through a complex geological landscape where Jefferson, Madison, and Gallatin counties converge. In the late 1980s, this area was defined by the industrial presence of the Burlington Northern railroad, which follows the river's path past the small settlement of Sappington. To the northwest, the prominent Lewis and Clark Cavern State Park marks a transition into the elevated London Hills, while the surrounding terrain is etched with evidence of small-scale extraction, including several Prospects and Mines Shafts Prospects. The map captures a high-desert environment where water sources like Huller Springs and Round Spring were critical landmarks. Notable for its surveying of jurisdictional boundaries, the sheet shows the exact triple-county junction southeast of the main river bend, providing a detailed look at the rural infrastructure of Summit Valley and the drainage patterns of Little Antelope Creek.
