Well yes, of course. That's what
ANYONE does when "hiding" a fabulous treasure: They riddle the site with "giant markers". In order to "mark" the thing they just "hid".
First thing I would do is look for a Unique Spot.
One with Immovable Objects whether those objects were Marked, or not. Or
Or shaped like animals, walls, or Whatever, And then I'd look around for a Spot
like Caves, Crevices or whatever to hide things in.
if non exist I'd look for the Closest Spots that can be Dug.
If I Have an Army with me.
After it's Buried, I'd consider having them move some of the large Rock Terrain
on the Freshly Dug & Covered Hole to make it look as Natural as Possible.
Figuring When I Come back, I Know I'll need Dynamite or an army of Trusted Men
to Help. re dig it. but preferably less then I'd needed to use to Hide it.
and call it a day.
unless of course if I was that Paranoid.
and Unscrupulous enough to off everyone else who knows, too.
But Treasure Signs can even be CK & LW forever in a Heart . or 666.
A WW2 Treasure could be Buried under a Spanish Direction Marker.
If the burier figures they will remember the Spot Better
Don't Rule out that "100% Natural" Boulder that looks like Groucho Smoking a Cigar
that blew up in his face
I'd wager People have Buried Caches at or Near Billboards
on the Lonely Roads to LasVegas.
Just so they Have money for the Trip home if they Crap out in Vegas.
