Abstract: Method and apparatus for constructing an ice structure. The disclosed ice structures are a road and a grounded ice island which are constructed on a sheet of naturally-occurring ice in an ocean. A vehicle equipped for driving on ice includes thereon a rotatable grinding wheel which may be urged downwardly against the ice over which the vehicle is driven, thereby generating ice chips which are collected on the vehicle. The chips are mixed with water to form a slurry which is pumped through a hose to a portable sprayer through which the slurry is sprayed, thereby forming the ice structure.
