Hidden Cache locations

[Uniq]

I have been searching xb19 for like an hour and I cant find the cache, Found one of the fakes but nothing else. It was by the junkyard.
This is making me nuts, been drigving between them like 20 times and nothing,

This one drove me nuts too, the dense dust clouds made it very difficult to see anything.

Try looking by the wrecked pirate base, close to the edge of the map...
