The movement of cryoturbate ground on a 21 ° slope at Grytviken, South Georgia was studied by observing the positions of stones resting on the surface and stakes buried vertically to depths of 10, 25 and 50 cm. The surface stones moved throughout the seven snow-free months an average distance of 47 cm, but movement of the stakes, the amount of which varied with their depth of burial, took place only during the spring thaw and following heavy autum frosts. Movement was confined to the upper 25 cm. and was predominantly due to the formation and thawing of ice lenscs within the soi.
