The first waterfall to encounter on the bike ride is Chamana, far away across the other side of the river valley. The rock glistens both with dewy wetness and silica composition, giving a plasticy/metallic sheen to the landscape.

I notice this waterfall actually as the chain falls off my bike's gears: switching from second to first apparently has unintended side effects. After examining the complex contraption for a few minutes I discover that, contrary to my fears, it's possible to re-set the chain wtihout getting covered in grease (a big concern when you only have a single outfit of clothing). I replace the chain and decide "Who needs second gear anyway?".
