A short, succinct book by a geology professor from the world-famous Colorado School of Mines. Dr. Keating is very strong on explaining how to meet federal requirements for posting and filing your placer mining claim. Practical advice includes not getting into arguments with other (crazed) prospectors. Fool's gold is the only mineral with a color similar to real gold but it is brittle and hard. "Put a particle or two of the metal on a glazed saucer or any other very smooth hard surface. Then, with the point of a pocket knife, 'smear' the speck as if our were attempting to spread a pat of butter. If it is gold, it will flatten into a thin yellow flake."
