If you like to dig for diamonds, head on over to the Ace, it's the place! More

Totally not worth it. Very rude people who only want to take your $9.50 and set you off to a pile of junk. They lie to you and tell you that you are better off looking in the picked over piles when they really know the best stuff is in the walls & digs. Most all (~ 95%) of the... More

Very beautiful landscape. Be prepared for weather and conditions. I highly recommend reading and checking out the Ace of Diamonds website for information. The "diamonds" are rather easy to find for young and old. This is a great destination to explore and I have tremendous fun every time I go. I only went a few times last summer and found... More
