Hey Bill96,
In my opinion.........Penfield is higher caliber than most. I would suggest when you initally read a story about lost.....whatever, look at AND research the writer's sources. When you see; 'Lost Treasure', 'Desert Mag.'.......'Western-Eastern' as the only sources, look at your hole card....a couple times. I want......DEMAND to see !@#$% Historical Soc., !@#$% State Archives, !@#$%'s day to day Diary as sources. Then I research,on my own, to verify the info was written by, no more than, second-person to the deed. I want to have dated verifiable info, written AT THE TIME, AT THE PLACE, BY THE PEOPLE INVOLVED or as on the spot witnesses, perhaps as a current newspaper issue that was written by someone who was reporting a current event. If the 'treasure story' has merit, this info is fairly easy to get, if you perservere.
People tend to believe.....most things they read in a treasure magazine or books by people with 'PHD' after their name and 'guruize' (think I invented a word) the writer. A case in point is 'Terrible Trail- Meek Cutoff' by Clark and Tiller. I read this book, cover to cover, twice before I started using it as a page-by-page resource. there is a ton of good 'source' info in it. I know two different....teams(not me) of treasure hunters who used this book as 'gospel' and trudged the Malhuer breaks for weeks following Clark and Tillers directions.
I did go to Eastern OR to scope out the 'S Chambers' headstone ('Find the grave and you will find the gold'). Talk about a 'credibility come-uppance'. Coincidentally, my trade for thirty years was Journeyman Bricklayer/Stonemason. I have cut and faced a......crap-load of stone, from granite to lava for veneers, fire-place faces....whatever. This 'gravestone was supposed to have been faced and carved overnight, between days walking daylight til dark by a greiveing(spelling?) husband with tools of the day, he had with him. NOT! COULDN"T HAPPEN! It took someone many hours, if not a couple days to carve this thing. Also, There is no stone in the area that matches it. It's not local stone. FIRST STRIKE.
SECOND STRIKE was when I read a passage where they cited Jesse Harrit's diary(could have been Parker or Field diary. Don't have my research in front of me). He said 'Traveled AGAIN a little West of South today'. The 'authors' corrected him saying, (paraphrasing) 'He thought he was traveling SW but he had to be traveling NW as three days hence he was at.....' The 'grave' was the denominator for ALL diary entries. If it did not jibe with the grave location(a known spot) it was ignored out-of -hand or INTERPRETED. NOW......We're talking about a fella who got up and started walking from Missouri, driving oxen, EVERY MORNING with the sun on the back of his neck. He walked all day and before dusk he had the sun in his eyes. Please do not tell me he did not know South from North.
THIRD STRIKE; (paraphrasing)Field's diary entry of Sept. 9 (had my wife dig up my diary copies), talks about a child that died. They had a quick funeral and drove the WHOLE WAGON TRAIN over the grave to hide it. Seems they had been told the indians in E. OR had a penchant for digging up the dead and stealing the clothes. NOW......In one case they make a huge point(documented) to hide a grave,.....in another they build a.....monument, sticking up like a crapper in the fog.; same train, same people, same indian problem......Enter a Mr. Reaves, the man who searched for the grave for yyyyeeeeaaaarrrrs, found it and told everyone where it was. Anyone but me have a problem with this discrepancy

Is it possible (read probable) the grave-stone is a plant to lead searchers away from the real area
Anyhow....I'm on a rant. Please do your own investigation and use your head. Most times it's better than some writer's head, him needing to sell a story or book.
