1926 Map of Hell Creek

About this map

The high-country drainage of Willow Creek and the eastern edge of the Caribou National Forest define this 1924 survey of the Idaho backcountry. Settled life centers on the community of Dehlin, where the Dehlin School and Pipe Creek School served local families. The landscape is characterized by its complex network of seasonal and year-round water sources, including Willow Springs and the expansive Fall Creek Basin. The topography is marked by significant landmarks like Jumpoff Hill and Fine Mtn, which straddle the border between Bonneville and Bingham counties. This map captures a moment when land divisions were anchored by the Boise Base Line, providing a clear look at early 20th-century montane ranching and forest land before significant modern development altered the creek systems and cattle ranges.
