Sand dunes, dune fields, playa lakes, playa sediment plumes, blowouts, and scour streaks can be recognized from LANDSAT imagery (resolution ∼80 m) and high-altitude aerial photography (resolution ∼5 m). The abundance of such features in the southern Wyoming test area confirms a major wind corridor with local areas of extremely strong winds indicated by concentrations of eolian features. The abundance of sand and semiarid climate of the area are also important factors in the development of eolian features.

Elongate eolian features indicate the direction of flow of strong winds through the area. Streamlines interpreted from these directional indicators parallel streamlines...
