During late fall and winter of 1977, personnel from the Center for Archaeological Research, The University of Texas at San Antonio (UTSA), conducted limited test excavations and controlled surface collections along portions of the Salado Creek drainage in northern Bexar County (Fig. I). Four specific areas were examined, as they were soon to be inundated or critically altered by proposed floodwater retarding structures. The sites in these locations had previously been identified and recommended for further work by Hester et al. (1974). During field operations, the areas of Floodwater Retarding Structures 3, 6, 10 and 15 were investigated. A total of four terrace sites, two small rockshelters and two rockshelter complexes were tested. Of the shelters, one complex and one individual shelter, both previously unrecorded, were discovered in the immediate vicinity of the retarding structures during the course of testing operations. Testing was concentrated in the immediate vicinities of Mud Creek, Panther Springs Creek and portions of the main channel of Salado Creek
