Mammoth Lakes: SR-203 : Mammoth Mountain

Tucked along the eastern flank of the Sierra Nevada, Mammoth Lakes is a place whose character is shaped by high-altitude volcanic terrain and deep winter snow. Mammoth Mountain rises immediately southwest of town, while the Mammoth Lakes Basin holds a chain of alpine waters including Lake Mary, Lake Mamie and Twin Lakes. The area sits close to the Long Valley Caldera, one of California’s most prominent volcanic landscapes. Mammoth Mountain Ski Area, operating since 1953, has made the town a major base for skiing and snowboarding as well as summer hiking, cycling and fishing.

California occupies a long Pacific coastal belt in the United States. Its terrain ranges from the Sierra Nevada and the fertile Central Valley to deserts in the southeast and the rugged shores of the Pacific Ocean. The state includes both Mount Whitney, the highest point in the contiguous United States, and extensive protected lands such as Yosemite National Park. California’s cities have exerted worldwide influence through film, technology, agriculture, and music; Hollywood remains an enduring symbol of the American screen industry. Its scale means climates and local character can change dramatically from one county to the next. Continue through nearby webcams to explore different parts of California.

The Atlantic, Pacific and Gulf coasts define much of the United States — their ports, fisheries and trade routes have long tied the country’s economy to the wider world. Between them, the Rocky Mountains, Great Plains and Mississippi River basin form sharply different regions, from high western ranges to broad agricultural heartlands. Cities carry much of the national story: New York’s Statue of Liberty, a gift from France dedicated in 1886, remains an enduring symbol, while Washington, DC concentrates major federal institutions. Indigenous nations have shaped these lands for millennia, and their living cultures remain essential to the country’s identity.
