A young rockhound show his friend a ledge featuring outcroppings of iron-stained quartz veins bearing low grade silver. These veins were not considered economic to mine and left in place.

Park personnel and a geology professional recently discovered a rock on park grounds containing dozens of ounces of silver. Despite that thrilling find, it would take much, much more, a mountain more, to profitably reopen the old workings.
