Chocolate Hills, Philippines

So-named because they resemble little mounds of chocolate in the dry season – when their grassy coverings go from verdant green to brown – these otherworldly hills have puzzled scientists for decades. The peaks, which spread across 19 square miles (50sq km) on the island of Bohol in the Philippines, vary in size but have strikingly similar and symmetrical shapes as if created in mounds. The most widely accepted hypothesis is that the hills were formed by the weathering of limestone. As tectonic plates shifted, the limestone was lifted above sea level and the hills were gradually sculpted by rain, wind and erosion. Another theory is that the hills are in fact former coral reefs, brought above sea level due to a geological shift. Myths and legends on the island provide plenty of other ideas, suggesting they were formed by the tears of a heartbroken giant – or that they were created when two battling giants threw rocks at each other.
