Archaic land use of upper Leon Creek terraces: Archaeological testing in northern Bexar County, Texas

During a three-week period in March 1995, the Center for Archaeological Research (CAR) of The University of Texas at San Antonio (UTSA) conducted the second phase of archaeological work at 4lBX47 under contract with Pape-Dawson Engineers. This phase of intensive testing was designed to assess the significance of the Early and Middle Archaic deposits identified during the 1994 CAR survey of the 147-acre project area (Tennis and Hard 1995). These investigations were performed to further comply with U.S. Army Corps of Engineers permit requirements. Fieldwork consisted of fourteen 1-x-1-m test units, 59 Gradall trenches, and additional geomorphological investigations. Eight-four burned-rock features were located, one with a radiocarbon date of 8955 (8655) 8545 B.P. associated with a Paleoindian period Angostura point. The results of this work verifies the 1994 findings of intact Early and Middle Archaic components as well as newly identified Late Paleoindian and Late Archaic components. Site 41BX47 is significant and is eligible for inclusion in the National Register. The mitigation of areas associated with the Late, Middle, and Early Archaic and the Late Paleoindian components offers potential to address important research issues concerning hunter and gatherer adaptations in south-central Texas.
