Thanks, Jeff! I'm always interested in any authentic research material, even that which cannot be easily proven.
While employed at The Oregonian Publishing Company, was able to use the Oregon Historical Society's Research Library for several months. Found most of Ruby el Hult's original sources, and was able to track down several related ones.
One of the most important IMO was a reference to an early issue of Sunset Shores Magazine, which later evolved into Sunset Magazine. This issue was back in the 1880's, and detailed a document on parchment or velum found inside a hollow rock cairn on Neahkahnie Mountain, and may well be the original description of the Neahkahnie Treasure. Unfortunately one of the original curators of the library felt it was too rare to leave out for anyone to see, and apparently added it to one of his many scrapbooks. He knew where it was stored, but almost impossible for anyone else to find it. When the curator died, a separate card index had to be created for the over 300 scrapbooks he made. Those scrapbooks are truly a treasure trove for treasure researchers.
The original document was in Spanish, and not many people in Oregon spoke any Spanish until much later. Tends to *prove* there was something going on in the area from early Spaniards. Chief Concommolly, once told his son-in-law, Dr. John McLoughlin, that Concomolly was the grandson of a shipwrecked Spaniard enslaved by the Tillamook tribe. He later escaped, and travelled north, where he eventually joined the prestigious Tchinook tribe, married, and produced a son. Most people will recognize the Neahkahnie Treasure story as the basis for the movie "Goonies", although it was never had a pirate in it. I don't think it was coincidence that much of "Goonies" was filmed on the northern Oregon coast.
