Otherworldly Landscapes

On the Philippine island of Bohol, nearly 1,300 grass-covered, limestone mounds called the Chocolate Hills dot an area of approximately 20 square miles. The mounds range from 100 to 400 feet high. In the dry season, the hills look like giant chocolate chips. Legend says they were formed by a defecating giant buffalo given food poisoning by vengeful local farmers, but scientific evidence suggests that they were created either by limestone weathering or volcanic debris.
