I wonder how old that road is. Maybe it was used as a landmark when the cache was buried. The road seems to be "pointing" at the target location. Even triangulating to it with the other bend to the south-east. Interesting...
When you say they've been checked, do you mean you went to two of the marked locations and scanned with your gadgets? Were you able to get any signals?
One of them is an old ruined church that I’ve found Many war relics and some coins and the other is a place I’ve already checked many times and I have gold signals! But there are large rocks that have fallen over the place logically after a landslide.. It's a shame because I have a signal from all of my detectors.
Definitely old sites in there; White something underground, purple ancient, green general archaeological, red surface metal detecting. Gold color for gold.
The gold coin caches made by guerrilla fighters were away from the water more inland, their bunkers heavily booby trapped with trip wires. Bunker caches the gold coins put in ammo cans.
