Redmond Hunt Trophy RockTrophy Rock is an all natural mineral supplement to provide deer with the electrolytes and trace minerals they need for optimum health. How do I use it? Placing Trophy Rock in staging areas or near bedding areas usually works best. We recommend placing Trophy Rock on a stump or another flat rock keeping it up off the ground. It will last much longer in the field if you avoid mud puddles. We have also found deer to be much more relaxed at mineral sites
