A method and apparatus are provided for forming an ice slot in an ice sheet by cutting discrete blocks of ice in the ice sheet, then gripping the blocks of ice with a claw-like attachment extending from a hydraulic arm and pushing the ice blocks downwardly with the hydraulic arm until the blocks reach a level with the underside of the ice sheet and then rotating the blocks under the surrounding ice sheet, whereby loads on the ice sheet are reduced and the ice blocks contribute to the load capacity of the ice sheet due to the buoyant upward pressure of the ice blocks.
