Sexton Glacier is located in the U.S. state of Montana in Glacier National Park. The glacier is situated in a cirque north of Going-to-the-Sun Mountain and on the southeast slope of Matahpi Peak at an elevation between 8,000 feet (2,400 m) and 7,000 feet (2,100 m) above sea level.[3] The glacier covers an area of approximately 68 acres (0.28 km2) and lost over 30 percent of its surface area between 1966 and 2005.[2]
