Look! Each water droplet flinging into the air towards us weighs, approximately, five hundredths of a gram depending on it's size. Most of Sumidero Canyon's walls are between 200 and 700 meters tall, reaching nearly a kilometer at the highest point - weathered down by time, the archaic groaning of the Earth, and from these little drops of water that flitter along the canyon walls. Is that not incredible? The time required for such things is unimaginable to us, and yet still is the natural order of our world. The water here is as skilled an artisan as any - a stonecutter as well as a gardener, nourishing vines and moss and all manners of vertically-inclined foliage that appreciate the view over the canyon. Towards the bottom, water-lillies and flowers grow in alcoves and nooks, vines resting half-submerged in the water. In some corners, deep and comfortable enough, river crocodiles mark time and anticipate visitors.
