David,
That is an awesome photo (and the story is great too)! My wife and I rode a Harley through that area this past July and unfortunately the weather was not as beautiful as the day your photo was taken. I was about 55-60 degrees and nothing but rain from south of Old Faithful to Jackson Hole. My wife is a trooper and never complained......She's a keeper!
Now, about the rest of the buried treasure.....any engine parts???
