This Cache Rocks Traditional Cache

Get ready for another clastic cache! This one shouldn't erode or petrify your brain power too much to find. Somewhere in this relatively new park there's a true gem of a container hidden for you. Don't quarry if you cant find it as the hint gives some pretty concrete spoilers as to what you're looking for. (stealth may required) THANKS FOR ALL THE FINDS, SADLY THIS CACHE HAS BEEN MUGGLED
