Lyell Glacier is in the Sierra Nevada of California. The glacier was discovered by John Muir in 1871,[2] and was the largest glacier in Yosemite National Park. It lies on the northern slopes of Mount Lyell.[3]

The glacier has retreated since the end of the Little Ice Age in the mid-19th century. 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.[4] Another glacier, the Maclure Glacier on nearby Mount Maclure, has also retreated significantly.

According to a study in 2013, today the Lyell is no longer a glacier, having lost any movement and thus it should considered an ice field.[5]
