RESPONSE TO COMMENTS BY HARRISON

In our article "A Reexamination of Red Linear Style in the Lower Pecos Canyonlands of Texas," we presented the results of an analysis of 444 Red Linear style pictographs from 12 sites in the region. Using this greatly expanded data set, we produced a list of diagnostic attributes for the style and documented stratigraphic relationships among pictographs through macro- and microscopic field analysis. We identified 38 examples of Red Linear under Pecos River style, a style previously assumed to be older than Red Linear. No Red Linear figures were identified superimposing Pecos River style. These results were verified by an independent group of archaeologists and chemists engaged in the analysis of Lower Pecos rock art. We concluded that Red Linear style is either older than or contemporaneous with Pecos River style. In Harrison's comments, he argues that our methods were faulty and the data inadequate to support our conclusions. We address a few of Harrison's critiques in our response; however, a more careful reading of the original article and supplemental materials is advised.
