(Whidbey Island, WA)  --  Researchers will try to determine whether an anchor recovered off the coast of Whidbey Island is historic in nature.  The "Seattle Times" reports the 900-pound anchor was recovered yesterday from the Strait of Juan de Fuca.  The "Times" reports amateur historians believe the anchor broke free from the HMS Chatham, companion to British Captain George Vancouver's HMS Discovery, during his voyage into Puget Sound in 1792.  The anchor, which is now in Port Townsend, will be transported to Texas A&M University, where the research will be conducted.
