![]() Finally, pictographs are providing richer detail of prehistoric hunting techniques than was previously available. Other styles proposed by Bilbo and Bilbo (1991) can possibly be resolved through absolute dating. One terminal Archaic rock art style (the Red Linear Style, defined in the lower Pecos River in Texas) has been identified as similar to elements at several sites in the Guadalupe Mountains (Mark and Billo, 2010, in press). 1000-1250) has allowed preliminary comparison of that panel to undated Site LA 71921. Digital enhancement photography of a panel from the BLM's Richard Brown Shelter (A.D. In mixed component rock art sites, x-ray fluorescence (XRF) may assist in separating and confirming element assignment. Direct absolute dating of the rock art sites will greatly strengthen arguments that identify and separate pictographs into age-related components or styles. Dating the fine line rock art is difficult because of the absence of associated artifacts and archaeological deposits and because of a general Archaic lifeway that continued into the historic period. ![]() ![]() Comparable fine line rock art appears in canyon settings in southwest Texas. Abstract symbols from low elevation sites on the east side of the Guadalupe range are similar to those found in mountain sites while representative fineline hunting scenes appear to be mainly confined to the Guadalupe Mountains themselves. Volunteers and federal agencies are combining their efforts to locate and investigate rock art sites, mainly pictographs, found in the southern portion of the Guadalupe Ranger District, Lincoln National Forest, and upon lands administered by the Bureau of Land Management, Carlsbad Field Office. ![]()
