I am going back a couple of days with this sketch – done after we had done a short day hike to the top of Nagpatong rock in Tanay Rizal, last Saturday. The hike ended with us climbing up some precarious ladders to the top of this rock, where we had some fantastic views. Apparently this is karst terrain – an area made up of soluble limestone, that has slowly eroded and dissolved, forming sinkholes, caves and springs.
