Abstract

Locational data for 96 allochtonous blockfields distributed throughout the Appalachian Mountains of eastern USA were obtained using TerraServer, an online resource for viewing air-photo and satellite imagery. Palaeotemperatures calculated using known Appalachian lapse rates and published LGM temperature departures indicate that most blockfields in the study area were formed under climatic conditions conducive to permafrost. Complementary use of these resources and spatial-analytic techniques holds considerable potential for addressing the broad-scale problems with which traditional climatic geomorphology is concerned
