Andrews Glacier is an alpine glacier in a cirque below Otis Peak (12,486 ft (3,806 m)) in Rocky Mountain National Park in the U.S. state of Colorado.[2] The glacier extends from Andrews Pass at nearly 12,000 to 11,700 feet (3,700 to 3,600 m) with some perennial snow extending to Andrews Tarn, a small proglacial lake. When images of the glacier taken in the early 1900s are compared with those of the early 2000s, Andrews Glacier is showing a negative glacier mass balance which indicates the glacier is retreating.[3]
