Modern and ancient eolian avalanche strata
Fryberger SG and Valdez A. Modern and ancient eolian avalanche strata. Research Permit and Reporting System
Avalanches can initiate anywhere on a dune slipface, although they most commonly start near the brink of the dune where most grainfall accumulates and slopes are steeper. Whether an avalanche reaches the bottom of the slipface depends upon two primary factors: (A) The thickness and downslope extent of the grainfall layer; that is, how deeply the slipface is covered by fresh, unstable sand and (B) the shape of the dune, particularly the steepness of slope.
