About this map

Bancroft and the Gentile Valley define this late 1940s landscape, where the Union Pacific (Oregon Short Line) cuts across the northern plains. This area is a complex network of agricultural irrigation and hydroelectric power generation, evidenced by the intricate system of the Gentile Valley Canal, Soda Canal, and Lloyd Canal. In the south, the Bear River powers the Grace Power Plant and Cove Power Plant, supported by visible surge tanks and penstocks.

The topography transitions sharply from the irrigated valley floors to the high peaks of the Portneuf Range, including Sedgwick Pk and Petticoat Pk. Small settlements like Lund, Talmage, and Central are linked by local family roads such as Taylor Road and Barfuss Road. For historians, the presence of the Leadville Mine and various high-altitude basins like Fish Creek Basin illustrates the early mining and ranching interests that shaped this Idaho-Bannock county border region.
