2020 Map of McCammon

About this map

McCammon serves as the focal point for this study of the Portneuf Valley, where modern infrastructure meets the high desert landscape of southeastern Idaho. The town's grid, including streets like Bannock St and State St, is positioned at a critical geographic junction where the Portneuf River emerges from the mountains to meet the broad Marsh Valley. This area demonstrates a complex relationship between natural water systems and early 20th-century engineering, evidenced by the Portneuf Marsh Valley Canal winding through the valley floor alongside Marsh Creek. To the east, the terrain rises sharply into the Portneuf Range, much of which is protected within the Caribou National Forest. The mountain landscape is deeply etched by features like Mullen Canyon and Dry Canyon, while historical pathways such as the Lower Robbers Roost Trail near the namesake Robbers Roost suggest the region's rugged frontier history.
