摘要：In the fall of 1997, Prewitt and Associates, Inc. conducted archival and oral history research, an archeological survey, and National Register testing of a prehistoric site in the vicinity of the San Felipe Springs in southeastern Val Verde County, Texas. The work was done in preparation for construction of a water treatment plant and related facilities for the City of Del Rio. The survey resulted in the recording of one historic site (41VV1820) and further documentation of historic and prehistoric components at a previously known site, 41VV444. The latter site also was the focus of intensive geoarcheological investigations. National Register testing of 41VV444, called the San Felipe Springs site, was restricted to portions of the alluvial terraces of San Felipe Creek near the East and West San Felipe Springs. A 40-m' block excavation near the East Springs revealed three stratified prehistoric components in the upper ca. 100 m of alluvium. These sediments represent continual deposition over the last 3,000-4,000 years, and archeological materials denoting Late Prehistoric, Protohistoric, Late Archaic, and Middle Archaic occupations were recovered. The upper component post-dates A.D. 1300 and produced plain bone-tempered potsherds, ClifIton and Perdiz arrow points, and steeply beveled scrapers. This component represents a Toyah phase occupation on the western periphery of the Toyah culture area, but it shares many attributes with Protohistoric Infierno phase occupations of the Lower Pecos. The middle component is characterized by Shumla dart points and three pit features originating near the base of a dense burned rock layer. It represents utilization of the area during the Flanders Subperiod of the Late Archaic. Although recovered from many sites (particularly rockshelters), the chronology of Shumla points is not well established in the region. Radiocarbon assays place the age of the San Felipe Springs Shumla component at ca. 800-200 B.C. Geomorphic evidence suggests that a major flood episode (or episodes) occurred along San Felipe Creek between ca. 1300 and 800 B.C. This gravelly deposit separates the middle component from the lower component and is indicative of a high volume flood event, possibly similar to the August 1998 flooding along San Felipe Creek resulting from Hurricane Charley. Underlying this zone is a discrete Middle Archaic occupation containing a dense burned rock layer and an internal pit feature. Radiocarbon dates, along with associated Bulverde and Langtry variant dart points, correlate to the San Felipe Subperiod.
