Dead-ice occurs when a glacier or ice sheet ceases to move and melts in situ. After the ice has melted it leaves behind a hummocky terrain produced by the deposition of glacio-fluvial sediments and ablation till as the ice melted. Such features include kettle holes.[1] Landscape forming Veiki moraines in northern Sweden and Canada have been ascribed as the result of ablation of extensive bodies of till-covered dead-ice.
