HRA’s archaeologists have extensive knowledge and experience in all phases of archaeological investigation. We work closely with State Historic Preservation Offices (SHPOs), federal and state agencies, Tribes, ethnographers, corporations, and other partners and clients to understand and meet specific project and resource needs. Our work is completed according to HRA’s robust safety protocols, and we follow strict confidentiality measures to protect sensitive archaeological and ethnographic information. We strive to provide an inclusive understanding of archaeological resources and historic contexts through scientific investigations and analysis, historical research, and inclusion of perspectives and interpretations of people from the pertinent non-dominant culture(s), in particular those of Indigenous voices and the voices of other communities and people of color.
