The Treasure Rocks of Neahkahnie Mountain, is no doubt the most important collection of information ever written about the area. It's difficult to over estimate the importance of the facts that you present here. Well done!!" Bob La Du, Ph.D., Portland, Oreogn. 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 Wayne Jensen, how he and Donald Viles made their discovery of the survey, its subsequent verification by Phil Costaggini and Robert J. Schultz, A.S.C.E., Oregon State University Master's thesis "Survey of Artifacts at Neahkahnie Mountain Oregon", and how the incised markers were eventually deciphered by the author.
