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 feet (2300 m) and 7200 feet (2200 m) above sea level. A half-mile south of Lake Nooney and Lake Wurdeman Hudson 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.
