摘要

Continuing water damage to adobe and masonry structures in the Upper Ruin (AZU:8:48), Tonto National Monument, required archeological excavations to mitigate the adverse effects of stabilization efforts in this Gila-phase cliff dwelling. New data derived from the analyses of the recovered cultural materials and ancillary investigations conducted as an integral part of this project will require adjustments in the National Park Service's interpretation of this National register property. In particular, the first, formal absolute dates for the occupation of the shelter were generated as part of this stabilization project. Dendrochronological dates and radiocarbon assays now place the occupation of the cliff dwelling as early as A.D, 1303 and potentially as late as A.D. 1473. The site and domestic structures are now considered to represent an occupation that began during either the late Roosevelt phase (Early Classic period) or the early Gila phase (Late Classic period).
