In 2004 I began my dissertation research at the archaeological complex of Acaray in the Huaura Valley, Peru. The project was funded by a Dissertation Travel Grant from the UIUC Graduate College. Mapping, intensive surface analysis, and surface collections were carried out. Mapping focuses on recording topography and major architectural features. Defensive features such as parapets (see image below), bastions, defensive walls, and access routes were documented, and a geographic information system (GIS) was implemented to carry out spatial analysis of the site and surrounding area. Additional indicators of defense were documented, such as abundant rolled river cobbles associated with defensive walls and parapets that were probably used as projectiles (see image of slingstones below), and a few lithics that may have been weapons (porra fragments and projectile points). Surface collected pottery indicated a primary occupation dating to the Late Intermediate Period (LIP, ca. 1000-1476).
Additional mapping and excavations were carried out in 2005-2006. This phase of research was funded by a Fulbright-Hays Doctoral Dissertation Research Grant and a Wenner-Gren Foundation Research Grant. Excavations revealed that defense was not the only activity in which the people of Acaray were engaged. Indications of ritual activity suggest Acaray was more than just a fortress (see images of textile below). This field season also permitted the identification of a previous occupation of the fortress during the Early Horizon (ca. B.C. 900-200), when the fortress was probably first built. Radiocarbon dating confirmed that the fortress was in use during both the Early Horizon and LIP.

In 2006 my colleague Alejo Rojas Leiva and I began analyzing a collection of quipus and quipu fragments recovered in one of the cemeteries at Acaray. With funding by the Exploration Fund of the Explorer’s Club a detailed registration of the collection was carried out. This find indicates a likely Late Horizon component (Inka presence) at Acaray that has yet to be investigated.
