From Gold Rush to Ski Mecca

The history of this place begins not with skis, but with gold mines. In 1877, four prospectors staked claims on Mineral Hill south of the modern settlement, and by 1878, the Mammoth Mining Company had been organized to extract minerals. It was in honor of this company that the town got its name. For a long time, gold was mined here, but when the mines were exhausted, the settlement was almost forgotten. A new chapter began with the development of skiing. Mammoth Lakes was officially incorporated on August 20, 1980, becoming the only municipality in Mono County. Today it is a year-round resort that attracts visitors for extreme skiing and unique nature.

Geological Wonder of the Sierra Nevada

Mammoth Lakes sits at an elevation of 7,880 feet (2,402 meters) above sea level, and at the base of Mammoth Mountain the elevation reaches 9,000 feet (2,745 meters). But the main geological feature is its location in the Long Valley Caldera. This is one of the largest volcanic calderas on Earth, measuring approximately 32 km long and 18 km wide. The region remains one of the most geologically active areas in North America with ongoing seismic activity caused by magma movement. In May 1980, a series of earthquakes reminded everyone of the magmatic resurgence in the caldera. Scientists warn that there is enough molten magma here for a potential supereruption comparable to the catastrophe 700,000 years ago.

Swimming in Boiling Water: Hot Springs

Volcanic activity has gifted the region numerous thermal springs. There are 11 natural hot springs in the Mammoth Lakes area, including Travertine Hot Springs and springs along Hot Creek. The most famous is the Hot Creek Geological Site, located in the volcanic depression of the Long Valley Caldera. Here, boiling geothermal springs bubble through the river gorge, coloring the rocks in fanciful mineral layers. Swimming in the creek itself is prohibited due to boiling surges, but there are safe pools nearby where you can relax after a day on the slopes.

Snow Records of Mammoth Mountain

Mammoth Mountain is a composite volcano located in the Inyo National Forest and one of the snowiest places in California. In the 2022/23 season, a state record for seasonal snowfall was set here — 870 inches (about 22.1 meters), breaking the previous record of 695 inches. Such precipitation makes the resort a true paradise for freeriders and backcountry enthusiasts. You can watch the snowy slopes not only in person: Mammoth Lakes webcams online allow you to assess weather conditions and snow depth in real time without leaving home.

Devils Postpile: Basalt Organ

Near the town lies the Devils Postpile National Monument — an amazing geological formation. It formed about 100,000 years ago when basalt lava filled a valley, creating a lava lake 122 meters deep. As it cooled, the lava cracked, forming perfect hexagonal columns resembling a giant organ. This place is a must-visit if you find yourself in these parts. And if you're just planning a trip, Mammoth Lakes webcams will help you assess road conditions and weather in the region in advance.

What the Cameras Show

To observe life in this unique settlement, various online streams are available. Mammoth Lakes cameras are installed at key locations: Mammoth Mountain slopes, downtown streets, lakes, and ski lifts. You can watch in real time the weather, snow cover, and traffic in the city. The live broadcast is available for free and without registration, making trip planning as convenient as possible. Choose a location you're interested in and enjoy views of the volcanic caldera and snow-capped peaks.
