The Crushed Stone Industry Grows Up: A History of Mineral Material Trespass on Public Lands in Central Arizona

Crushed stone is the product resulting from the artificial crushing of rocks, boulders, or large cobblestones, substantially all faces of which have resulted from the crushing operation. BLM generally considers crushed stone sources a saleable mineral, which must be purchased from BLM. Some producers focusing on the Phoenix metropolitan area have searched for ways to avoid purchasing these minerals, thus avoiding payments to the BLM. One of the more common ways is to claim that the mineral material is “locatable” instead of saleable.
