Between April 30 and June 3, 1998, the Center for Archaeological Research of The University of Texas at San Antonio conducted subsurface testing for cultural resources along the proposed route of a water pipeline for Southwest Texas State University. The area to be impacted by the proposed waterline included a tract on the banks of the headwaters of the San Marcos River and tracts adjacent to the Aquatic Biology Building. The project area is partially within the known boundaries of site 41HY161. The archaeological investigations included shovel testing, backhoe trenching, excavation of three 1 x 1-m units, and monitoring. Upon completion, based on the results of this archaeological work, it was determined that no intact cultural resources would be impacted by the planned trench construction between the west bank of the San Marcos River and the southeast corner of the Aquatic Biology Building. However, intact cultural deposits were identified west of the Aquatic Biology Building dating to the late Paleoindian and Archaic periods. Therefore, clearance for the pipeline route was recommended in areas that did not contain cultural resources and in areas disturbed by recent or historic construction. To avoid disturbance to intact cultural materials, Southwest Texas State University was required to modify the depth of the pipeline trench west of the Aquatic Biology Building.
