Along with being declared the 3rd National Monument, the Chocolate Hills have been recently included in the new nominations for the seven wonders of the world. These hills are a unique and unusual geological formation. Spread across 50 sq. km, (20 miles approx.), the Chocolate Hills consist 1268 to 1776 dome-shaped hills, covered in grass. So, how did they get their name? Well, the hills are covered in green grass almost all year round; however, in the dry seasons, this grass turns to a chocolate brown color. Hence, they are called ‘Chocolate Hills’.
The height of these hills ranges between 150 to 400 feet. Whereas, the height of the domes varies between 98 to 160 feet ( 30 to 50 meters). The highest peak in these hills measures 390 feet (120 meters). These hills are spread across the towns of Sagbayan, Carmen, and Batuan in Bohol.In geographical terms, such a hill is called a geomorphological structure, also known as a mogote. For many years, geologists have tried to decode the mystery of the formation of these hills. Most of these theories say, that these hills were formed because of a major geologic shift, when coral deposits rose up from the sea. The dome-like shape was formed due to the erosion of these deposits by wind erosion, through thousands of years.
