At the posted coordinates, climb the rocks and look to your feet. You'll meet a sleeping concrete giant on the shore. If he were to stand up and follow the paved path to the other side of the cove directly south, he'd reach the perfect shelter for a cache on his right. He might have to watch his head and shins as he entered, but just about giant-sized eye-level he could spot the cache in its hiding spot.
Please leave the stamp inside the container for the next letterboxer.
