In his memoirs, Virgil Barnes recounts highlights of his life and career in entertaining detail: his childhood in Washington; his worldwide travels in search of tektites, accompanied by his wife, Milla; and his geological mapping and other research during his 58 years at the Bureau of Economic Geology and in retirement. Barnes began his long and prolific career at the Bureau in 1935. He directed the mapping project that resulted in 38 Geologic Atlas of Texas sheets and the four-quadrant geologic map of the entire state of Texas.

This report documents the stratigraphy beneath playa lakes and associated lake-margin, playa-basin, and upland settings. Genetic facies interpretation of the observed lithologies was undertaken to better predict the nature of interplaya stratigraphic variation and to extract information about the long-term geologic and paleoclimatic evolution of the area.ABSTRACTPlaya lakes are abundant small ephemeral lakes (generally ~0.5 km in area) that occur in shallow depressions (generally <11 m deep) on the surface of the Southern High Plains.
