Abstract

The surface of the Southern High Plains is dotted with thousands of small (<5km2), circular, seasonally dry depressions, or playas, some of which are accompanied by a crescentic dune ridge, or lunette. The playas are inset into the sheets of eolian sediment that blanket the region (Blackwater Draw Formation) and the lunettes rest on the eolian mantle. Statistical analysis was undertaken to better understand the origins and development of playas, and their relationships to lunettes. Data support the hypothesis of playa development by erosion rather than by dissolution and subsidence. Lunettes most often are associated with deeper and wider playas. Presence or absence of lunettes probably is related to the nature of the playa fill and is not a function or substrate texture. Lunettes form from deflation of calcareous playa fill which is more common on larger playas. -from Authors
