While walking around on the beach at Great Lake Huron in Pinery Provincial Park in Grand Bend, Canada you could see the sand and rocks were unusual. The large sand dunes and tall pine trees hid the beach but once you got down there there was a large section of the beach that were round stones. They were glowing and extremely colorful having Green, Blue, Gold, Brown and almost every color. Most rocks were granite with multi colors but there were slate and limestone rocks mixed in with even some fossils.
