On the higher dune ridge, niveo-aeolian deposition also extended the top of the dune, but the result was an oversteepening of the slip face.
Measurements of sand accumulation around pins on the lee slope of the dune indicate that deposition is concentrated on the upper slip face during the fall and winter leading to oversteepening (37[degrees]) towards the crest.
