Cultural Resources Survey and Monitoring of Joint Task Force Six (JTF-6) Actions in Webb, Zapata, Dimmit, La Salle, Duvall, and Jim Hogg Counties, Texas

Joint Task Force Six (JTF-6) Operation AT-93 involved multiple actions in six south Texas counties. These actions included the repair and construction of approximately 240 km (150 mi) of existing firebreaks, the repair/upgrade of approximately 9.5 km (5.9 mi) of road along the Rio Grande River near Laredo, the upgrade of two small-arms firing ranges, and the construction of a fitness/obstacle course. Extensive previous disturbance was noted within the impact areas of the firebreaks and at the two firing ranges; no cultural resource sites were located in these areas. Along the Rio Grande, the survey identified the site of Star Fort (part of historic Fort McIntosh), which was crossed by the road improvement project. The proposed fitness/obstacle course is located within an old industrial area, which has been previously determined to lack significant cultural resources. The sites of Star Fort and the San Ygnacio Historic District were recognized as National Register properties that needed to be avoided. Avoidance of these properties was successful except for the grading of an existing road adjacent to the remains of Star Fort that had been marked for avoidance. Fortunately, this action resulted in no damage to the historic property. In summary, Operation AT-93 resulted in no impacts to the cultural resources of the region
