1964 Map of Sharp Mountain

About this map

Sharp Mountain rises as a central landmark within the high terrain of the Wasatch Cache National Forest, where the headwaters of several major drainage systems converge. This 1960s survey, updated in the mid-1980s, highlights a landscape defined by its complex hydrology and early industrial traces. Evidence of mineral exploration is preserved at the La Plata Mine located within La Plata Canyon, north of the Right Fork Ogden River. The map meticulously tracks the dividing ridges between the Cache and Weber County line, showing how the mountains partition the flow toward the East Fork Little Bear River in the north and the multi-branched Middle Fork Ogden River system to the south. The presence of Sawmill Canyon and various 4wd tracks suggests a history of timbering and resource extraction across Porcupine Ridge, serving as a record of land use in this part of northern Utah before modern development.
