I'm sure some individual will at least have the thought of trying to dig the site out. I've had the same thought over the years, I confess! People need to realize (as I have) that this thing is bigger than any individual, the legend and lore of the Lost Dutchman / Peralta mine is known throughout the world.
And, the sight is being monitored more closely than you might think. I suggest to everyone: go see it, take pictures until your camera battery goes dead, walk around and investigate the area. This is history and it should be seen by everyone who chooses to do so. When you retire from the canyon at the end of the day, leave it as you found it so others will have the same opportunity you had.
Over the years I've stood inside the funnel shape of the mine a hundred times and each time I've decided to leave it alone. The reason I leave it alone is simply because it's the right thing to do for all the dutch hunters, the people of Arizona, and the people of the country. As I stated before, this is far bigger than any one individual will ever be.
