OWSA-Survey offers a full range of Cultural Resource Management service. Over the last 40 years we have conducted thousands of class III cultural resource surveys, scores of site testing and evaluations and about a dozen large-scale data recovery excavations for public and private organizations. No project is too small and we have the experience and resources to effectively and efficiently complete all but the largest multi-state projects. We can provide complete turn-around for most small class III surveys in a matter of days. In addition to archaeological field investigations, OWSA-Survey offers a range of specialized petrography services for advanced ceramic and stone analyses.
