Dune Dune
A medium to large-scale depositional sedimentary structure consisting of a ridge-like accumulation of sediment (sand or gravel) formed by flowing water or wind. The migration of a dune forms cross-stratification. Dunes and associated cross-stratification are good indicators of current (paleocurrent) direction.
