About this map

Swanlake and its vital Union Pacific rail sidings anchor this late 1960s study of the Bannock and Franklin County border. The landscape is defined by the sharp contrast between the high peaks of the Portneuf Mountains, including Heart Mountain, and the low, marshy reaches of Oxford Slough and Swan Lake. This corridor was clearly essential for local agriculture and transport, evidenced by the presence of a Grain Elevator and a Storage Bin alongside the railroad tracks.

Industrial and community markers are scattered across the valley floor, from the local Cem to several Gravel Pits. Water management is a primary theme of the terrain, seen in the drainage from Stockton Creek and Dry Hollow toward the basin. The southern portion of the quadrangle opens into Poverty Flats and an extensive Alkali Flat, illustrating the transition from alpine slopes to the arid, mineral-heavy flats characteristic of this region.
