A note on needle‐ice mound formation in the High Drakensberg, Southern Africa
Abstract Small needle‐ice mounds are described from the High Drakensberg. They develop infrequently during periods of several days of uninterrupted cold conditions. Ice growth incorporates sediment and stones. An accumulated segregated ice length of >41 cm was measured, with clasts heaved ∼14 cm....
