The cache is not at the posted coordinates.
I've driven through this valley a few hundred times and it is always a wonderful place, except during the inversion. The plants grow and the animals start very small then grow. What a great place. A couple of months ago I spotted this view and here is a puzzle for you to solve. Hopefully you'll enjoy the picture as much as I do.
When you go to the cache, I suggest you park on the short street rather than in the park and go. Then walk along the field. Good luck.
Here is a link to the puzzle.
