The Lyell Glacier, the largest glacier in Yosemite National Park, has stagnated, or ceased its downhill movement, according to a recent study conducted by scientists from the National Park Service and the University of Colorado.
The adjacent Maclure Glacier is still moving at its historical rate, about one inch a day.
Glaciers are defined as long-lasting ice masses that arise from the accumulation of snow, and move downhill by flowing and sliding, according to the park.
