Coming down from the rock, Yapahuwa, Sri Lanka.

In sylvan surroundings while climbing down.

A series of holes has been bored into the side of a granite hillock. This could be the remnant of an old technology to break the rock. A series of holes were made into the granite. Wooden pegs were then hammered into the holes. Water was poured onto the wooden pegs. The wooden pegs would soak up the water swell up and break the rock in a cleavage plane. The work on the rock has apparently been abandoned.
