I don't think there's any Filipino child who went through grade school who does not know the world famous Chocolate Hills and why they were called that way. And I'm not sure if what they know up to this day is correct.
You see, I finally reached Bohol last weekend and was able to clarify this.
From what I know back in gradeschool, the hills are brown during rainy season and green in summer. It's actually the other way around according to Kuya Bobet, our very honest very informative tour guide of Bohol.
During summer, the grasses gets burned by the heat of the sun hence getting only that brown color. Inly grasses grow on these 1000 something hills because the major component of the hills is limestone, not friendly for te trees and other bigger plants.
I suddenly felt the urge to go back to my school and tell my grade school teacher, who obviously not been to Bohol, to stop teaching what she's been teaching for the past 20 years.
