Reevaluating the antiquity of the Palmrose site: Collections-based research of an early plank house on the northern Oregon Coast.

Large-scale excavations conducted by Smithsonian Institution archaeologists and avocational archaeologists during the 1960s and 1970s at three sites in Seaside, Oregon, resulted in the recovery of a diverse range of material culture curated by multiple institutions. One site, known as Palmrose (35CL...
