Thousand Island Lake is a large alpine lake in the Sierra Nevada, within the Ansel Adams Wilderness in eastern Madera County, California.
The lake is named for the many small rocky islands that dot its surface. Theodore Solomons probably established the 'Thousand Island' name, as this appears on his 1896 map. John Muir called it by "Islet Lake."
The lake is within the boundaries of the Ansel Adams Wilderness of the Sierra National Forest and Inyo National Forest. Thousand Island Lake sits at the base of Banner Peak in the Ritter Range. It is the source of the Middle Fork of the San Joaquin River, which flows southeast, and then west, into the San Joaquin Valley. The lake is a glacial tarn, formed in the bottom of a cirque when a glacier retreated.
Thousand Island Lake is accessible from several hiking routes:
The black and white photographs by Ansel Adams made Thousand Island Lake a famous Sierra landmark.[ citation needed ]

The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas.
The John Muir Trail (JMT) is a long-distance trail in the Sierra Nevada mountain range of California, passing through Yosemite, Kings Canyon and Sequoia National Parks. From the northern terminus at Happy Isles in Yosemite Valley and the southern terminus located on the summit of Mount Whitney, the Trail's length is 213.7 miles (343.9 km), with an elevation change of approximately 47,000 feet (14,000 m). For almost all of its length, the trail is in the High Sierra backcountry and wilderness areas. For about 160 miles (260 km), the trail follows the same footpath as the longer Pacific Crest Trail. It is named after John Muir, a naturalist.
The Ansel Adams Wilderness is a wilderness area in the Sierra Nevada of California, USA. The wilderness spans 231,533 acres (93,698 ha): 33.9% of which is in the Inyo National Forest, 65.8% is in the Sierra National Forest, and the remaining 0.3% covers nearly all of Devils Postpile National Monument. Yosemite National Park lies to the north and northwest, while the John Muir Wilderness lies to the south.
Mount Whitney is the tallest mountain in the contiguous United States and the Sierra Nevada, with an elevation of 14,505 feet (4,421 m). It is located in East–Central California, on the boundary between California's Inyo and Tulare counties, 84.6 miles (136.2 km) west-northwest of the lowest point in North America at Badwater Basin in Death Valley National Park at 282 ft (86 m) below sea level. The west slope of the mountain is in Sequoia National Park and the summit is the southern terminus of the John Muir Trail which runs 211.9 mi (341.0 km) from Happy Isles in Yosemite Valley. The east slope is in the Inyo National Forest in Inyo County.
Devils Postpile National Monument is a National Monument located near Mammoth Mountain in eastern California. The monument protects Devils Postpile, an unusual rock formation of columnar basalt. It encompasses 798 acres (323 ha) and includes two main tourist attractions: the Devils Postpile formation and Rainbow Falls, a waterfall on the Middle Fork of the San Joaquin River. In addition, the John Muir Trail and Pacific Crest Trail merge into one trail as they pass through the monument. Excluding a small developed area containing the monument headquarters, visitor center and a campground, the National Monument lies within the borders of the Ansel Adams Wilderness.
The John Muir Wilderness is a wilderness area that extends along the crest of the Sierra Nevada of California for 90 miles (140 km), in the Inyo and Sierra National Forests. Established in 1964 by the Wilderness Act and named for naturalist John Muir, it contains 581,000 acres (2,350 km2). The wilderness lies along the eastern escarpment of the Sierra from near Mammoth Lakes and Devils Postpile National Monument in the north, to Cottonwood Pass near Mount Whitney in the south. The wilderness area also spans the Sierra crest north of Kings Canyon National Park, and extends on the west side of the park down to the Monarch Wilderness.
Sierra National Forest is a U.S. National Forest located on the western slope of central Sierra Nevada in Central California and bounded on the northwest by Yosemite National Park and the south by Kings Canyon National Park.

The Minarets are a series of jagged peaks located in the Ritter Range, a sub-range of the Sierra Nevada Mountains in the state of California. They are easily viewed from Minaret Summit, which is accessible by auto. Collectively, they form an arête, and are a prominent feature in the Ansel Adams Wilderness which was known as the Minaret Wilderness until it was renamed in honor of Ansel Adams in 1984.
Mount Ritter is the highest mountain in Madera County, California, in the Western United States, at an elevation of 13,149 feet (4,008 m). It is also the highest and most prominent peak of its namesake, the Ritter Range, a subrange of the Sierra Nevada in the Ansel Adams Wilderness of the Inyo and Sierra National Forests. Mount Ritter is the 15th highest mountain peak in California with at least 500 meters of topographic prominence.
Inyo National Forest is a United States National Forest covering parts of the eastern Sierra Nevada of California and the White Mountains of California and Nevada. The forest hosts several superlatives, including Mount Whitney, the highest point in the contiguous United States; Boundary Peak, highest point in Nevada; and the Ancient Bristlecone Pine Forest that protects the oldest trees in the world. The forest, encompassing much of Owens Valley, was established by Theodore Roosevelt as a way of sectioning off land to accommodate the Los Angeles Aqueduct project in 1907, making the Inyo National Forest one of the least wooded forests in the United States' system.
Mount Williamson, at 14,379 feet (4,383 m), is the second highest mountain in both the Sierra Nevada range and the state of California. It is the sixth highest peak in the contiguous United States.
Mount Russell is a peak in the Sierra Nevada mountain range in the U.S. state of California, about 0.8 miles (1.3 km) north of Mount Whitney. It rises to an elevation of 14,094 feet (4,296 m) and is the seventh-highest peak in the state.
