Abstract

Research completed during the 1970s through the early 1980s developed lichen dating curves for 5 regions in the Arctic and subarctic mountain ranges beyond altitudinal and latitudinal treelines. Comparison of results from recent moraine-dating studies based on these 5 lichen dating curves with tree-ring based glacier histories from southern Alaska shows generally good agreement, albeit with greater scatter in the lichen-based ages. Cosmogenic surface-exposure dating of Holocene moraines has the potential to test some of the assumptions of the lichenometric technique and to facilitate the development of a new set of improved lichen dating curves for Alaska
