Glacial rock.

A glacial erratic is a rock, or cluster of rocks, that was picked up, carried away, and deposited elsewhere by ice, like a glacier. Generally, the glacial erratic is different from the bedrock rock on which the erratic sits. That is, a glacial erratic is a foreign rock that generally does not come from the immediate area.
