Early Holocene Paleoindian deposits at Nall Playa, Oklahoma Panhandle, U.S.A

Abstract

Fieldwork conducted at the Nall North locale and the adjacent playa documents buried Paleoindian deposits and a stratigraphic sequence dating back to the late Pleistocene. Cultural debris recovered from the surface of Nall North includes bone, tools, and lithic flake debris. Two buried paleosols at the locale date to the early Holocene and hold high potential for Paleoindian materials. The Baker paleosol, a stabilized surface above the shoreline of the adjacent playa lake, dated between ca. 6870 and 7740 yr B.P., contains a rich cultural component of tools, flakes, and bone, and represents a potential surface for Angostura and Allen/Frederick artifacts. Located below the Baker soil is the Nall soil (dated to ca. 9650 yr B.P.) that probably represents a marsh facies of the playa fill. The Nall soil represents a potential surface for Plainview/Goshen-age artifacts, although excavations thus far have recovered no cultural debris. In the playa adjacent to the Nall North locality, a sequence dating between ca. 12,960 and 5310 yr B.P. documents localized spring flow into the playa during the late Pleistocene, followed by several thousand years of playa muds during the early Holocene, and the eventual drying of the playa in the middle Holocene. © 2003 Wiley Periodicals, Inc.
