Hudson Glacier

Hudson Glacier is located in the US 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 7500 ft and 7200 ft above sea level. A half-mile south of Lake Nooney and Lake Wurdeman, Hudson Glacier covers an area of approximately 8 acre and does not meet the threshold of 25 acre 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.
