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."[2]

Geography[edit]

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 San Joaquin River, which flows west into the San Joaquin Valley. The lake is a glacial tarn, formed in the bottom of a cirque when a glacier retreated.[3]
