Just rocks. The guy has a vivid imagination and a little learning.
If there ever was anything on Weyerhauser property they would obliterate it. They have plowed, planted, built roads and otherwise disturbed that country since the 70s. Before that Dierks Lumber was all over it and before that Choctaw Timber Company cut ALL the old growth off of it everywhere they could reach. It did not take long to destroy all pristine traces of the forest from the post Civil War years.
In the 70s there were a few old men who remember other old men telling them the old growth pine were so big and thick there was almost no under story brush. You could see deer 100 yards away.
My uncle found some runic stones while building fish ponds along the Kiamichi River near Albion. The dirt contractor claimed he had found “many”. I am doubtful. No evidence was ever produced.
There are no minerals in SE Oklahoma to speak of. It is all just sandstone and shale. Some quartz to the East in Arkansas but that is all.
SE Oklahoma as to have been largely uninhabited until the Choctaw relocation. Just rugged country with good rainfall but dry mountains and slow running muddy creeks and rivers.
I looked at the link of pictures on Comment #1. One object called Geologic Oddities was a broken open geode showing fine crystals, probably quartz inside. You can see lots of this kind of thing at rock and gem shows. The question should be was this kind of geode common where it was found or has this been imported from a site far away.
The collaboration of Gloria Farley and Dr. Fell has produced lots of fascinating information. I have read Ms. Farley’s book “They All Discovered America.” If you can see a copy you will be amazed at how many different groups may have traveled to the US and left their graffiti—often near small rivers that boats could travel along. Also included are alphabets from 4 or 5 ancient civilizations, some dated back to 2 to 4 thousand years ago. There are specific chapters on a number of different topics—animal figures, ancient religious images, specific enscriptions such as possible Scandinavian runes, Celt-Iberian script, Punic, etc. Well worth finding a copy if this is a big topic for you.
