In the summer of 1981, the second season of excavations at the Rancho de las Cabras (41 WN 30) was conducted by the Center for Archaeological Research, The University of Texas at San Antonio, for the Texas Parks and Wildlife Department, Austin, Texas. This season included further architectural testing and stratigraphic excavations in a large trash pit located during season one, July 1980. A five by six meter area of the interior northwest corner was excavated revealing wall trenches and floors of part of a jacal complex. A more exact plan of Rancho de las Cabras was drawn, and professional surveyors from the Texas Parks and Wildlife Department made a contour map of the site. Recommendations for future historical and archaeological research are included in this report
