Cross-section of icing (aufeis) in front of Fountain Glacier (B26)
This is an image of the same icing depicted in images 0145, 0146, 0152, 0153, 0154, 0155, 0156, 0183, 0194, and 0195. An icing is defined in the American Geologic Institute's Glossary of Geology (p. 310) as .. "A surface ice mass formed during the winter in a permafrost area by successive freezing of sheets of water that may seep from the ground, or from a spring or river." In Brown and Kupsch (1974), icings are further described as forming "from freezing of overflow water or seepages from rivers; they may extend onto land surfaces and are therefore ...called floodplain icings." Dr. Brian Moorman has carried out extensive research on this particular icing, both as part of his Ph.D. dissertation at Carleton University in Ottawa and in research he has done more recently. This work was instigated by the visit that Professor Fred Michel (Carleton University) and I made to this site at the time these photos were taken in 1991. The ridge in the left background is the outer slope of the neoglacial lateral moraine of Stagnation Glacier (B28); (see images 0085, 0143, 0145, 0151, 0166, and 0183).
