David Harder M.A., R.P.A.

Principal Investigator

David grew in eastern Washington with an early exposure to archaeology and agriculture.  His familiarity with land use issues instilled in him a curiosity regarding indigenous subsistence and early historic settlement. This interest led to his undergraduate studies of archaeology and the pursuit and completion of a Master of Arts degree in Anthropology; specializing in archaeology. His studies emphasized Columbia Plateau archaeology and prehistory with a focus on the Lower Snake River.  He has received formal classroom and field training in many aspects of archaeological method, theory, and research including the Section 106 process, NEPA and historic properties, lithic analysis, faunal identification, and geo-archaeological method and theory.

David has enjoyed a 30 year career as a professional archaeologist, working predominately in the region populated by the Plateau Cultural groups. This has allowed him to follow his chosen vocation while using his multi-faceted knowledge of the region.  While conducting fieldwork for wastewater treatment plants and storm drains isn’t Indiana Jones level excitement, David is proud of the work that Plateau has completed in the region that has contributed to the quality of life in the region.

His family has always been involved in agriculture, especially sheep, cattle, and some crops in decades past.  His parents ventured into poultry and operated a hatchery and small butcher plant for many years. David’s favorite bird is the duck, both as farm livestock and when properly roasted, and is working with Ducks Unlimited to provide quality habitat on the family ranch southeast of Ritzville.  David currently lives in Pullman with his wife, Jenny. They have been challenged to keep up with their three boys through Scouts, snow skiing, and other outdoor pursuits, as well as the next phases of their lives in high school and college.
