Lyell Glacier is a small glacier in the Sierra Nevada of California. The glacier was discovered by John Muir in 1871 [1], and is the largest glacier in Yosemite National Park. The glacier lies on the northern slopes of Mount Lyell.[2]
The glacier has retreated since the end of the Little Ice Age in the mid 1800s. During the mid 20th Century, the glacier split into two smaller glaciers occupying the high cirques of Mount Lyell.
Since 1883, the glacier area has retreated up to 70 percent.[3] Another glacier, the Maclure Glacier on nearby Mount Maclure, has also retreated significantly.
