Long ago, in what is now Central Utah, Native Americans noticed deer herds gathering to eat the soil. The animals had discovered the remains of an ancient sea bed, rich in salt and other natural minerals. Trophy Rock and Four65 come to you mined directly from this same ancient mineral deposit- nothing added, nothing removed. Trophy Rock products are a safe and cost effective way for deer on your property to restore electrolytes and much-needed trace mineral for optimal growth all four seasons of the year.
