The spheres are stone balls made of granite. They vary in size from about the size of an orange to giant balls measuring more than six feet in diameter and weighing 16 tons. All are perfectly round to within two centimeters
Thousands of these balls have been found along river beds and in ancient cemetery sites in the valley of the RÃ*o Térraba, located in the southwest portion of Costa Rica, and on Caño Island, nine miles off the Pacific coast. Some of them were found at locations more than fifty miles from the nearest site from which they could have been quarried. They have not been found anywhere else in the world.
