Hudson Glacier is located in the U.S. state of Montana in Glacier National Park. The glacier is situated in a cirque immediately to the east of the Continental Divide at an elevation between 7,500 feet (2,300 m) and 7,200 feet (2,200 m) above sea level.[3] The glacier covers an area of approximately 8 acres (0.032 km2) and does not meet the threshold of 25 acres (0.10 km2) often cited as being the minimum size to qualify as an active glacier. Between 1966 and 2005, the glacier lost more than 66 percent of its acreage.[2]
