- Blowout Dunes
Various saucer, cup, or trough-shaped hollows formed by erosion on a pre-existing dune or other sand deposit.
Vegetation is often found on blowouts.
Ed found various saucer, cup, or trough-shaped hollows on top of the dune. "Hmmm," he thought. "Must be blowout dunes." Then he had a nap.
