A mountain icefield of Loch Lomond Stadial age, western Grampians, Scotland

Abstract: The extent of a large mountain icefield that existed in the western Grampians during the Loch Lomond stade has been mapped. The main types of evidence used in establishing the limits comprise moraines, thick drift, fluvioglacial landforms, erratics, ice‐smoothed bedrock, striae, friction cracks and relict periglacial forms. Trimlines on 198 spurs, and various forms of glacial and periglacial evidence on 73 cols and in c. 200 cirques, enable the upper limits and morphology of the icefield to be reconstructed.

“…Numerous glaciers drained the southeastern side of the Younger Dryas ice cap, and their limits have been the source of several differing interpretations (Thompson, 1972;Sissons et al, 1973;Horsfield, 1983;Thorp, 1986). Our model shows (above) that the Rannoch Glacier reaches its limit relatively late in the stadial, but modelled glacier configurations show significant shortcomings at Callander, Menteith and Loch Lomond, and an overprediction at Loch Tay (Fig.…”

“…The legacy of this latter episode -the Loch Lomond Readvance (LLR) -is evident primarily in the western Scottish Highlands, where landforms and sediments indicate the former presence of an ice cap centred along the main axis of the mountains and several satellite icefields around its periphery (Thorp, 1986;Bennett & Boulton, 1993;Ballantyne, 1989Ballantyne, , 2002Golledge, 2007). Considerable research has been undertaken on both the extent and timing of these glaciers, enabling a reasonably complete picture to emerge (Fig.…”

“…These less-dynamic areas would have experienced less strain heating, raising the effective viscosity of the ice and favouring thicker, more sluggish and probably less erosive glaciers. Whether these thermodynamic contrasts are sufficient to explain the absence of erosional periglacial trimlines in eastern areas, in contrast to their abundance further west, remains an interesting avenue for future research (Thorp, 1986;Golledge, 2007a).…”

“…The LLS period was characterised by an abrupt return to severe cold conditions following ice sheet retreat when glaciers regrew, forming most significantly a large ice field running the length of the Western Highlands (Bennett & Boulton, 1993;Thorp, 1986). This ice field was the largest of numerous satellite ice fields, ice caps, valley glaciers and cirque/niche glaciers on several of the western isles and at other upland sites around Britain and Ireland (Golledge, 2010).…”
