In places covered by ice sheets during Ice Ages, such as Scandinavia and Northern North America, ice has moved and formed granite boulders (glacial erratics). One of the largest is used as the pedestal of the Bronze Horseman in Saint Petersburg. An ice sheet is a mass of glacier ice that covers surrounding terrain and is greater than 50,000 km² (19,305 mile²).[1] The only current ice sheets are in Antarctica and Greenland; during the last ice age at Last Glacial Maximum (LGM) the Laurentide ice sheet covered much...
