Hi red desertGold flake, I've been checking the map again, but for traces of past human activity. There seems to be a lot of both more ancient and very recent sites. You might want to check some spots for stored processed gold or man made gold objects also.The red boxes must be military relics.
These are the associations for most things I mark in red or green.
Red circles/boxes for loose battlefield relics, coins/jewelry or other artifacts of value, from surface down to 1-2 feet deep. Red Xs usually mark deeper loose coins or artifacts of value, caches, cave/tunnel treasure.
Green for archaeological type of hits, including military battlefields and also the non-metallic targets such as flint points, pottery, carved rocks/trees, old foundation sites, etc.
The color is going out on my old computer monitor, so if the color is off, let me know. I hope to soon have the new laptop with external monitor set up in it's place.
No snow, I think I'd not miss the cold for many years, if escaping it was possible.
On this photo the green box is archaeological of some type, but doesn't seem to be military. The white box might mean a little if caves were back there.[/QUOTHANKS , WILL CHECK IT OUT FOR YOU. WILL TAKE ABOUT 3 WEEKS
Green in general is a color indicator, I use for various other targets mostly archaeological (old ruins or foundations but especially those non-metallic objects such as Indian flints, glass, pottery, carved stone with treasure signs).
I spotted something in one photo looked interesting, cropped it then enlarged as much as possible. Do you have natural caves in this area?
