Schematic representation of tfie Prudhoe Bay terrain showing the spatial relationships among soils and terrain types. See Webber and Walker (this volume) for relationships with vegetation types. As a consequence of the thaw lakes, which continue to modify the land surface, both landforms and their soils range widely in age (Brown 1965). Radiocarbon dates of 9330 ± 150 and 8690 ± 145 were obtained from reworked organic materials beneath lake bottom deposits in a large active thaw lake in the vicinity of the Tundra Biome study area. These organic materials are believed to have been derived from a land surface(s) into which the thaw lake has expanded. interfluves with wide expanses of patterned tun- dra and relatively featureless, very wet, drained, or intermittent lake basins (Fig. 1). Because of the large mapping scale and the intimate association between ground pattern and soil type, most of the 10 relief elements recog- nized on the soils map (Plate I) are ground pattern forms. The characteristics of the forms generally follow a microrelief classification system developed for the Barrow tundra (Carey 1972). Certain modifications and additions to this classification were required by the Prudhoe Bay terrain. The terrain-relief classes used in Plate I are based on the character of the ground surface (its pattern or lack of pattern) and the amount of
