2011 Map of Mogg Mountain

About this map

Mogg Mountain and Mill Mountain define this high-elevation landscape in Lemhi County, serving as the headwaters for a complex network of alpine streams. This 2011 survey captures the drainage patterns of the Lemhi Range before major contemporary shifts in land management, showing the convergence of Hayden Creek and its many tributaries, including East Fork Hayden Creek and Tobias Creek. The presence of the Mill Creek Lake Dam indicates water management priorities in these steep canyons. Remote forest service routes like 010 and 006 provide the only access into these watersheds, where Patterson Creek and Falls Creek carve through the deep terrain. For researchers and geologists, the map provides a precise record of the hydrologic features that shape this portion of the Salmon River Mountains.
