calvin mako takes notes near a basalt cobble collected for surface exposure dating. calvin and the cobble are perched on the crest of a moraine ridge deposited by the ross sea ice sheet at the last glacial maximum. the view is to the southwest, with heald island and the koettlitz glacier in the upper left background. photo credit: Toby koffman.
Glenn mckenney cleans a cection near the mouth of miers valley. january 2011; the view is up-valley to the west. the white salt is probably thenardite, a sodium sulfate salt formed by the dehydration of mirabilite. radiocarbon dates from algae and shells collected in this section will indicate times in past when a grounded ice sheet advanced through the ross sea and mcmurdo sound. photo credit: toby koffman
A solar-owered differential gps is set up on a survey benchmark near the east end of Lae miers in january 2011. the i-196 (hall) camp is in the background near the south shore of the lake. adams glacier is on the left at the far end of the lake, and miers glacier is on the right. ross sea ice gounded in the mouth of the valley dammed a much larger lake during glacial times. gps elevations on deposits formed near the shore of this paleo-lake define a minimum thickness for the former ross sea ice sheet. photo credit: toby koffman
