2018 Map of Old Mammoth

About this map

Mammoth Lakes serves as the focal point of this 2018 survey, documenting the modern footprint of this Sierra Nevada community. The map illustrates the transition from the concentrated development at Old Mammoth and Mill City to the surrounding protected lands of the Inyo National Forest. High-altitude geology is a defining characteristic, with the Long Valley Caldera and volcanic landmarks like Earthquake Dome and Lookout Mountain framing the topography. Geothermal and hydrologic features are prominent, including the headwaters of Hot Creek and Mammoth Creek. Cultural history is noted through recreation and utility sites such as the Old Shady Rest Campground and the Old CCC Camp, while an extensive network of forest roads like the Mammoth Scenic Loop and Antelope Springs Road provides access across the volcanic flats of Smokey Bear Flat.
