1870 A. G. Girdlestone High Alps without Guides ii. 36 We could see into the great blue ‘schrunds’, in which innumerable and gigantic icicles depended from the roof.

1871 E. Whymper Scrambles amongst Alps (1900) xiv. 263 A schrund is simply a big crevasse.

1884 E. Whymper in Good Words Feb. 101/1 Schrunds or great crevasses.

1904 G. K. Gilbert in Jrnl. Geol. (Chicago) 12 573 Among the numerous crevasses or schrunds of several diverse systems sharply lining the snow surface.., one master opening, the Bergschrund of the Swiss mountaineers, paralleled the amphitheater wall... My instant surmise..was that this curving great schrund penetrated to the foot of the wall.

1904 G. K. Gilbert in Jrnl. Geol. (Chicago) 12 582 Usually in viewing a cirque it is possible to trace about its wall a somewhat definite line separating a cliff or steeper slope above from a gentler, usually scalable, slope below. This line I conceive to mark the base of the bergscrhund [sic] at a late stage in the excavation of the cirque basin. I have called it in my notes ‘the schrund line’.

1938 Geol. Mag. 75 262 This scarp..passes into the great vertical cliffs below Y Lliwedd so that the schrundline was present only on the side wall.

1939 Geogr. Jrnl. 94 462 Above the crevasse the surface of the glacier was covered by scree; and the material embedded in the ice, as seen in the bergschrund, is probably derived in some way from this surface material... A snow-bridge occurred 25 feet below the surface in the open part of the schrund.

1968 R. W. Fairbridge Encycl. Geomorphol. 741/2 Below the schrund line, where there is one, the cirque floor begins as a slope that bears marks of glacial abrasion.

1971 C. Bonington Annapurna South Face xii. 152 They were both worried by the huge overhang of snow that reared over the schrund like a breaking wave.
