Yes, gold fever has struck again in Idaho's Boise Basin.  Beginning in 1863, more gold was taken from here than from Alaska during the gold rush there, leaving behind a rich history and towns that thrive on tourism. Then when it was over it was over - until the price of gold skyrocketed, bringing forth entrepreneurs with their dreams.
Or are they more like fishermen?  If the fish don't bite you change the bait.  If that doesn't work you change fishing holes. That's what's happening here.  They dig,.using their various machines, and move to new locations to try again.  There's gold here.  That's a fact. It's just a matter of finding an economical way to get it out.
If gold is found again in quantity the world will know about it.  Until then, winter snows will cover the ground and we'll hope for a shining yellow spring.
