Springfield:
I do believe there are Spanish caches in the western portion of the U.S., but theirs are not the ONLY ones. I've come to believe that the Spanish were prospectors, but MAINLY scavengers who recovered and confiscated the old mining sites and caches left by others who were here long before the "great conquers" ever landed in South and Central America.
Starting in as late as the 19th century, I believe that there were well organized groups of nefarious people who developed their own codes based on the old ones for their own uses. They knew the codes were dependable so why change them very much? Just modify them a little bit to identify them as specific to THEIR group. An excellent example of this is the little triangular "flag" serifs on certain letters of the English alphabet as used by the Knights Templar (or if you prefer, the Scottish Rites Masons).
As I've written previously; there were many groups of people already HERE on the North American Continent WAAAAAAY before Columbus got lost. But to hear one person tell it; the only thing we (you) should pay any attention to is the trails left by the Spanish. Sorry, that leaves out too much history for me. I want to learn it ALL. At least as much as I can in the rest of my life. My health and personal situation does not allow me to travel out to the main areas of activity, so I live vicariously through the photos and experiences of others who ARE "out there". And many of those folks allow me to mark things in their photos that appear manmade or artificial while not trying to define their meanings. I usually ASK if they might mean such and such. But, because I've never claimed to be "expert" in this area, I NEVER try to label something as definitely one thing or another. I have openly left that to the more experienced and knowledgeable THers. I've learned during the past few years, that Old Dog, dsty, Desertmoons, ClayLindsey (sp), Oddrock, Rockhopper2, Tesoro Dog, tenclaw, HossKGC, and a few others whose words are solid and who do not condemn other folks questions, ideas, or viewpoints. I recently took you off of my "ignore" list after realizing that even though you don't agree with a lot of things posted here, you do not denigrate folks for disagreeing with you. I saw that I'd had the wrong idea about you and your observations. I'm trying to stay clear of the word "opinions" because opinions are like a--holes. Everybody's got one and most of them stink.

LMAO... Couldn't resist that one. Anyway, you make many excellent points and ask pretty pointed questions, but I don't recall you ever getting into the personal attack arena. I made one post about a comment you posted as being a good example of why I had put you on "ignore"..............for that I apologize. I should not have done that.
