The archeological site known as the Biderbost site was discovered in 1959 "after the Snoqualmie flooded, and revealed many basketry fragments, fishhooks, net weights, projectile points, adzes, chisels, choppers, scrapers, and knives. " This collection of basketry now resides at the University of Washington's Burke Museum in Seattle, and the excellent online site devoted to the collection examines "basketry objects more closely by looking at their origins on the Snoqualmie River, their excavation, weaving techniques, and the newest chapter in their lives as part of the archaeology collections at the Burke Museum." Visitors should begin by clicking on the Archaeology link at the top of the page; here they can learn more about the site and check out a short video where Dr. David Rice discusses the Biderbost Site. Visitors interested in the materials used for the baskets (which included spruce root, cherry bark and cedar) and the weaving techniques will find The "Basketry Technology" tab to be informative. Another short video can be found here, which provides the helpful explanations of a basketry expert to explain the process of analyzing the history of the basket, such as its uses and its quality.
