Thousand Island Lake, California

#575 of 610 in Nature in California
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."
