Here are two pics of caliche, calcium carbonate. Almost as hard as cement! The first is a large piece sticking out of the soil. If you find large sheets of this, unbrocken, you KNOW no one has been underneath it. Also sweep or vacuum the top of it for possible gold flour. The rock in my hand shows the left side coated with caliche. TTC
