This is the only place in the world where Calcite has formed in ancient Clam shells. You pick an area on the mound and dig some dirt, look for the Calcite in whole or partial clams. Wish your dirt with the provided hoses. I used one of Calvin Bumkers digging tools to dig and pull dirt to my wife to wash. You will also find loose Calcite. Be prepared to get muddy but also you will have a lot of fun and maybe get some valuable mineral samples.
