its collaborators. The north-Pacific coast is dominated by the volcanic basalts and hardened sedimentary rock that produce sea mounts and other dangerous rocks. Moving south, a mariner finds a very different geology in Marin County, CA where the San Andreas fault has moved the white cliffs north 300 miles over one hundred million years. Hydrography The sands at Drake's Cove and the general hydrographic nature of the Pacific coast have been investigated by the Guild and its collaborators. The levels of the sea have not changed significantly since Drake's visit. The sand spit shown on the Hondius Broadside map have been evaluated and found to have a cyclical nature – which has been shown by the reappearance of the sand spit in 1952 and 2001. Identification of the location of Drake's Cove The Guild recognizes Matthew Dillingham's photographic work on November 22, 1952 as the key break which allowed the identification of the specific Drake landing site. Marine expeditions The Guild has sponsored or co-sponsored several ocean studies of the Drakes Bay site. Since the discovery of Drake's landing site was by sea, it is critical to evaluate the landing site the way Drake and his crew saw it. One 1970s visit was aboard the USS Wiltsie (DD-716). The most recent expedition was co-sponsored by the Point Reyes National Seashore Association (PRNSA), Mother Lode Musical Theatre and the Guild on September 11, 2009. Navigation Drake traveled 1,500 miles north from Guatulco, Mexico seeking the Strait of Anian. Encountering bad weather, Drake headed east, finding land at Coos Bay, Oregon on June 5, 1579. The Guild has investigated the site. It took Drake 15 days to travel the 400 miles south to Nova Albion. The Guild has evaluated the navigation of this leg of his voyage. Recognitions Working with the English Navy and the Sir Robert Hadow, British Consul General, the Guild marked the landing site in 1954. An additional plaque was installed to honor the 400th anniversary of the landing in 1979. The Guild supported the marking of Drake's landfall in Oregon by the Oregon Historical Society and Oregon State Parks. In addition, the Guild led the work to establish the National Historic Landmark (2012) and the California Historical Landmark (#1061, 2021) which recognize the Drake's Cove landing site. Other investigations The Guild has led or participated in the research on several other Drake-related matters including Drake's First Landfall, the
