1992 Map of Glenns Ferry

About this map

The Snake River carves a critical corridor through the high desert of southern Idaho, serving as the historical and industrial lifeline for settlements like Glenns Ferry and Hammett. This 1992 topographic study details the transition from the irrigated valley floors of the Pasadena Valley to the expansive arid reaches of the Bruneau Desert and the Blackstone Desert. The map highlights the intersection of pioneer history and modern utility, tracing the path of the Emigrant Trail alongside the Union Pacific railroad lines. To the south, the landscape is defined by the massive Saylor Creek Air Force Range and the dramatic geology of Bruneau Canyon. Water management is central to the region's character, evidenced by the sprawling C.J. Strike Reservoir and the network of drainages such as Little Canyon Creek and Sailor Creek that feed into the main river system.
