Distribution of Glacial Deposits, Soils, and Permafrost in Taylor Valley, Antarctica

Figures & data

FIGURE 1 Generalized distribution of glacial deposits in Taylor Valley (compiled from Wilch et al., 1993; Hall and Denton, 2000b; Higgins et al., 2000a, 2000b; and unpublished data of Prentice and Bockheim). Colluvial, lacustrine, eolian, Alpine II, and Alpine I deposits are not shown. Blank patches are either the latter, bedrock, or snow.
