Vegetation-banked terraces on subantarctic macquarie island:A reappraisal
Vegetation-banked terraces with alternating bands of vegetation and gravel are spectacularly developed on the plateau of subantarctic Macquarie Island. Previous work has described two distinct, apparently unrelated types of vegetation-banked terraces on the island, "windward" and "lee...
