yes its real...like all the other treasure stories..."I found it,but now I need money to find it again"....want to know how it really happens in the real world of mining;
a guy or maybe several finally find what they have long suffered while looking for.They are excited beyond belief...maybe now they can send for their families they miss so badly.But instead of guarding it while help is aquired to exploit the find....they or he simply look around for a landmark and all leave together so they can get a cold beer and file a claim.
What do you know,the life altering,amazing,rags to riches find is now lost....because you know how the light plays tricks on you,and even though you actually lived there for a time....you just cant seem to find it.maybe if you tell enough folks,or show some placer gold you bought,you can get investors to finance an expedition which you will head to go look for it.
And heck,even if 150 years later it is proven untrue...heck write a book about it,make silly shows about it,the thing just never dies.
If a miner finds gold...he mines it.He never lets it out of his sight.He remembers where it is for gosh sakes.
