Shambles Glacier (67°20′S68°13′W) is a steep glacier 4 miles (6 km) long and 6 miles (10 km) wide, with very prominent hummocks and crevasses, flowing east between Mount Bouvier and Mount Mangin into Stonehouse Bay on the east side of Adelaide Island. It is the island's largest glacier, and provides an eastern outlet from the giant Fuchs Ice Piedmont which covers the entire western two-thirds of the island.
