“…They reflect hydrostatic pressure where uphill flow is possible in a down-ice direction, though modified by the detailed form of the topography (Shreve 1972). There are many classic descriptions of such channels in Scandinavia (Mannerfelt 1945;Holtedahl 1967), North America (Ives 1958) and Scotland (Sissons 1958). It seems reasonable to argue that those in coastal southern Victoria Land are similar and reflect the flow of a grounded ice sheet northwards and parallel to the coast.…”

. We illustrate here spectacular meltwater features associated with outburst floods beneath an ice sheet that overrode the Transantarctic Mountains in southern Victoria Land. Because of long‐term hyperarid polar climate, these features are part of an ancient landscape preserved for about 14 million years. Some channels are associated with areal scouring of basement rocks extending from sea level to as much as 1200–2100 m elevation in coastal regions. Scablands with scallops, potholes and plunge pools are cut in Beacon Super group sandstones and Ferrar Dolerite and cover wide areas of high western plateaus near the mountain crest. Subglacial channel systems commonly originate near divides and converge downhill toward the northeast. We argue that the landforms were created beneath a major Antarctic Ice Sheet that submerged the whole area, with the possible exception of the high peaks of the Royal Society Range, as it flowed northeastward toward the outer Antarctic continental shelf. Areal scouring, associated with warm‐based regimes, is restricted to the lower slopes close to the coast. In the higher terra in, meltwater channels and scabland alongside preserved patches of regolith are best explained by the breaching of cold‐based ice on the mountain rim by subglacial melt water outbursts. Melt from warm‐based ice, along with subglacial lakes trapped upstream of the mountain rim, are possible sources of the meltwater necessary to form the channel systems and scablands.

“…The work is typical of a programme of geomorphological mapping that began with John Rice (1959; and was continued and developed by Brian Sissons (Sissons, 1958;1967;Sissons and Smith, 1965;Sissons and Cornish, 1982) and a large number of his research students (for example: J.C.

This paper presents a 1:25,000 scale geomorphological map of the Glasgow region, western central Scotland, an area that was glaciated during the Last Glacial Maximum and, in part, during the Younger Dryas glaciation. The text accompanying the map sets out the historical context of the mapping exercise and describes the process of geomorphological mapping at 1:10,560 scale. The text outlines briefly the results of the mapping exercise, in terms of the map evidence recorded and the interpretation of Quaternary landscape evolution. The paper is not designed to provide a comprehensive review of the geomorphology and Quaternary history of the area which can be found in the references cited therein.

“…Mannerfelt, 1945Mannerfelt, , 1949. Particularly significant was a paper by Sissons (1958a) in which the influential ideas of Kendall (1902) on overspill channels were finally overthrown (see Ballantyne and Gray, 1984 and Evans, in press for review). There followed a large number of papers on the distribution and interpretation of glacial meltwater channels in Scotland (e.g.…”

“…Many of these were originally interpreted as glacial lake overflow channels Muff, 1901, 1903) but have since been explained as primarily of subglacial origin (Sissons, 1958a;Derbyshire, 1961;Clapperton, 1968). Classic examples include the Humbleton Hill and The Trows channels (Huddart, 2002b).…”

This paper reviews the evidence presently available (as at December 2003) in an effort to stimulate further research on the last British Ice Sheet and promote a reconstruction of ice sheet behaviour based on glacial geology and geomorphology. The wide range of evidence that has been scrutinized for inclusion on the glacial map is assessed with respect to the variability of its quality and quantity and the existing controversies in ice sheet reconstructions. Landforms interpreted as being of unequivocal ice-marginal origin (moraines, ice-contact glacifluvial landforms and lateral meltwater channels) and till sheet margins are used in conjunction with available chronological control to locate former glacier and ice-sheet margins throughout the last glacial cycle. Subglacial landforms (drumlins, flutings and eskers) have been used to demarcate former flow patterns within the ice sheet. The compilation of evidence in a regional map is crucial to any future reconstructions of palaeo-ice sheet dynamics and will provide a clearer understanding of ice sheet configuration, ice divide migration and ice thickness and coverage for the British Ice Sheet as it evolved through the last glacial cycle.2
