About this map

The La Plata Mine and its namesake La Plata Canyon anchor this high-elevation survey of the Cache National Forest, revealing the industrial footprints left by early mountain prospectors. Located along the boundary between Cache and Weber counties, the landscape is defined by the steep relief of Sharp Mountain and the prominent Porcupine Ridge. This terrain, heavily marked by mining activity and narrow drainage systems, shows a network of primitive 4wd routes that navigate between established points like Mineral Point and the depths of Little Bear River Canyon.

The hydrography of the region is particularly complex, featuring the headwaters of several critical forks. The Right Fork Middle Fork Ogden River and Left Fork Middle Fork Ogden River converge in the southern sector, while numerous named springs and creeks, such as Cinnamon Creek and Sawmill Canyon, indicate the vital water sources that supported both forestry and extraction in this part of the Wasatch Range.
