A good proposal, but in the wrong direction from where Adams started, plus much of the gold was found on the top of the hill (hence the name Rich Hill) which does not fit with Adams description.
I have to respectfully disagree with our mutual amigo Lastleg, though I am sure many will agree that the lost Adams was a myth, I am firmly convinced the mine and canyon did exist. One good piece of evidence in support of the story being true, is that Adams himself went looking for the mine, not once but several times. A man does not go off into the wilderness hunting a story he made up. Besides, Adams showed the egg-sized nugget to a number of witnesses, which I am sure many are happy to ignore but to me is another piece of solid evidence, for gold nuggets are fairly rare; only 2% of gold in nature occurs in the form of nuggets, they are not simply laying around everywhere for anyone to pick them up.
There are many theories about Adams and his mine, and probably very few would agree with me but it seems to me the simplest explanation is that Adams was telling the truth; (Occam's Razor) and no one has yet found his famous lost bonanza. Had it been found, the gold strike would have been in the news, as happened with a somewhat similar story with Goler's lost gold.
Good luck and good hunting amigos, I hope you find the treasures that you seek.
