Patterns of Lithic Use at AZ Q:1:42, Petrified Forest National Park, Arizona: Data Revovery along the Mainline Road

During Phase I of the project to reconstruct the Mainline Road (Pkg. 140) at Petrified Forest National Park, a two-component site, AZ Q:1:42, will be disturbed. To mitigate the impacts of the project, staff from the Western Archeological and Conservation Center conducted data recovery in August 1983. The site included four loci, two dated to the Basketmaker III period (A.D. 700 to A.D. 775) and two dated tentatively to the Pueblo II and Early Pueblo III periods (A.D. 950 to A.D. 1150). A large lithic collection from Locus B, an early component, and sample collections from the remaining loci were analyzed to recover both qualitative and quantitative data regarding spatial and temporal variability in lithic reduction stage and technique. A change through time in the lithic reduction strategy, as well as in loci layout, was documented.
