A sheet of ice is created on a sufficiently large body of water (at least 10 times the volume of the ice sheet). The sheet drifts with the current. The sheet is always circular and generally can not be guided or propelled by paddeling. The sheet can carry a weight of 50 x SI lbs. Under normal conditions the sheet volume remains constant for the spell's duration and deteriorates according to the weather and water conditions. (E.g. Salt water sheets melt faster.)
