Abstract This paper examines the evidence for cold‐climate conditions on Marion Island, both present and past, and discusses the palaeoenvironmental implications. Under present conditions frost penetration, except in the highest‐altitude areas, is limited to the upper 0.05–0.3 m of the soil. Relict periglacial features include large stone‐banked lobes and terraces, vegetation‐banked features and blockstreams. It is suggested that these features are the result of deep seasonal frost.
