About this map

The McCammon townsite serves as the central hub of this topographical survey, situated where the Portneuf River and Marsh Creek meet at the base of the Portneuf Range. The geography is defined by the broad Marsh Valley, which transitions into the steep canyons and timbered slopes of the Caribou National Forest to the east. Local history is anchored by the Harkness Cem and Norton Cem, which reflect the area's early settlement by pioneering families near the canyon mouths.

Water management and ranching infrastructure shape the landscape, notably seen in the Portneuf-Marsh Valley Canal winding along the valley floor. To the northeast, the terrain becomes increasingly complex with deep cuts like Mullen Canyon and Harkness Canyon. Historic pathways through the mountains are documented by the Robbers Roost Trl and Lower Robbers Roost Trl, tracing old routes through the Caribou National Forest.
