1964 Map of Sharp Mountain

About this map

Sharp Mountain rises over a complex drainage basin within the Cache National Forest along the high-elevation boundary of Cache and Weber counties. The landscape is dominated by the steep dissection of Porcupine Ridge and the headwaters of two major river systems. To the north, the East Fork Little Bear River gathers from Scare Canyon Creek and Cinnamon Creek, while the southern reaches of the map feed the various forks of the Ogden River. A localized history of resource extraction is evident at the La Plata Mine, situated near the head of La Plata Canyon. This area's geography is defined by deep drainages like Sawmill Canyon and Davenport Creek, illustrating the transition from high ridge lines to the tributary valleys that sustain the region's watersheds. The 1964 field check captures this high-country terrain before modern development, preserving the locations of remote mining sites and named springs.
