Small-scale deformations of glaciofluvial sediments is described from a Greenland outwash plain partly covered by icings (Aufeis, naleds). On the sudace these deformations takes the form of small ridges, parallel to the margin of the icings. Formation of the ridges is ascribed to processes during disintegration of icings, and the genetic term » Icing-ridge« is proposed. Icing ridges produced in a braided river envi- ronment are considered as most likely to be preserved at the base of small-scale coarsening upward sequences.
