ABSTRACT
J.T.Andrews et al. discussed the terrestrial and ocean paleoenvironment derived from morphostratigraphy, lithostratigraphy, faunal assemblages, and amino acid epimerization determined from shells in raised moraine sediments, which suggest warm inshore water conditions during the last glaciation. Late quaternary climatic changes in the Aleutian Islands, described by Robert F.Black, included details on ice-cap destruction and the advance and recession of alpine glaciers, changes in elevation of regional snowline, pollen stratigraphy, and tephra distribution. Alan V. and A.Morgan reviewed the history of paleoentomological research, and reported an abundance of organic detritus found in different stratigraphic horizons, including a rich assemblage of insects that are sensitive indicators of change in climate. Richard G.Baker reported evidence for interglacial and interstadial conditions produced by pollen and plant macrofossil remains from three sections in Yellowstone Park older than about 70 000 years.
