Pressure ice that is piled chaotically, one piece over another, to form an uneven surface. When weathered, hummocked ice has the appearance of smooth hillocks. This has a less definite form than rafted ice or tented ice, but in fact may develop from either of those as melting, sublimation, or drifting changes the sharper ice edges into more rounded shapes.
