rocksnrivers: I suspect that Santa Fe crackpot and self appointed savior of the free world Sal Maestas stole the cache and didn't bother to tell anyone.
Sal Maestas is on a tear to steal all caches placed in wilderness areas and firmly believes that he's doing a favor to the world.
It is his common modus operandi to impose his belief system upon everybody else. So if you own a cache placed in wilderness look out he's likely to snatch it.
You win Sal. I will no longer maintain this cache in YOUR mountains.
