Stone spheres of Costa Rica - Las Bolas
by Anne Watcher on Wednesday February 20th, 2008 at 8:42amThese stone balls were discovered in the Diquis Delta of Costa Rica in the 1940's while clearing land for banana plantations. Since then hundreds have come to light, some as small as a few centimeters, others over 2 m. in diameter. They have been know to weigh up to 16 tons. Almost all of them are made of granodiorite, a hard, igneous stone. As always many theories are circulated as to their origin.
The picture below is taken across the street from where we are staying at Norma's. They are about 1.5 m in diameter and they grace both sides of the entrance to a beautiful home. Based on our research about these spheres we are not prepared to say whether they are authentic or not. If we find out for sure either way, we will report back.
