The Treasure Rocks of Neah-Kah-Nie Mt. & The Symbolic Sovereign Act

During Francis Drake’s circumnavigation in 1579 while becoming the first
European to Captain to pilot a ship around the globe, he performed a survey on Neahkahnie Mountain as Symbolic Sovereign Act of a land claim by building cairns crowned with incised rock markers which have become known as the Treasure Rocks of Neahkahnie Mountain.
This narrative behind the Sir Francis Drake survey was conveyed to the author by Anthropologist and Director of the Tillamook Museum (1979-2003) Wayne Jensen; how he and Donald Viles, printer and former commercial fisherman made their discovery of the survey and its subsequent verification by Phil Costaggini and Robert J. Schultz, A.S.C.E., Oregon State University Civil Engineering Master’s thesis Survey of Artifacts at Neahkahnie Mountain Oregon. With the previous information made available to the author through the M. Wayne Jensen Library, some of the incised markers have been deciphered.
Post script: Since Treasure Rocks of Neahkahnie Mountain was published in 2012, additional markers have been deciphered and verified through Edward Wright's Certain Errors in Navigation (1599) and corroborated by the Edward Wright World Chart 1599.
