Global climate change is an increasing threat to cultural resources, especially in coastal areas. Archaeologists have responded with risk assessments that gauge these threats and create preservation priorities for land managers. However, most assessments do not include input from descendant communities, which limits their potential value and relevance to archaeologists and tribal partners. We are in the initial stages of developing a risk assessment model for the Lower Columbia that includes a process for collaborating with tribes. In addition to incorporating the existing archaeological and ethnohistorical data typically used in risk assessments, our project will also incorporate indigenous stakeholder priorities through peer-to-peer partnerships. This poster outlines our work so far.
