Andrews Glacier is an alpine glacier in a cirque below Otis Peak (12486feet) in Rocky Mountain National Park in the U.S. state of Colorado.[2] The glacier extends from Andrews Pass at nearly 12000to 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]
