Many people don’t realize that glaciers even exist in California. In fact, we have about 130. Most cling to steep slopes of the Sierra Nevada, but they’re disappearing at a rapid rate. Geologist Greg Stock of Yosemite National Park reports that even Lyell Glacier—second-largest in the Sierra—no longer has the mass required for it to creep downhill, which is one condition that defines a glacier.
