The previous version of the\r\ndigital atlas (v1) was originally available online in 2002\r\n(Manley and Kaufman, 2002). The evidence used to draw\r\nthe glacial limits in 14 regions across Alaska was described\r\nin a subsequent report (Kaufman and Manley, 2004), which was \r\npart of a larger effort to create a global database of \r\nPleistocene glacial extents with a target scale of 1:1,000,000. \r\nThis update (APG Atlas v2) is based on a more detailed map \r\nscale and, therefore, provides more accurately resolved limits \r\nof former glacier extents. In addition, the previous version\r\nincluded the only two glacier limits that could be most\r\nconfidently mapped and correlated around the state: \r\n(1) the all-time maximum extent of former glaciers; and \r\n(2) the late Wisconsinan extent (= late Weichselian = marine \r\nisotope stage (MIS) 2 = spanning the period between about \r\n24,000 and 12,000 years ago). In this update, we added \r\na third mapped limit for areas where it has been sufficiently \r\nwell studied, namely for the penultimate glaciation, which over\r\nmost of Alaska occurred during the early Wisconsinan.\r\n\r\nGlacier extent maps are available in Google Earth format at: \r\nftp://ftp.ncdc.noaa.gov/pub/data/paleo/alaska-glacier-atlas/alaska-palaeoglacier-atlas-v2.kmz \r\nor in ARC GIS format at: \r\nftp://ftp.ncdc.noaa.gov/pub/data/paleo/alaska-glacier-atlas/arcgis/ \r\n\r\nExposure ages are listed below, and in the equivalent Excel format file: \r\nftp://ftp.ncdc.noaa.gov/pub/data/paleo/alaska-glacier-atlas/alaska-palaeoglacier-atlas-v2.xls","version":"1.0","xmlId":"10024"}
