Most of the whiteish streaks seen on the mountainside are not actually waterfalls but "tree slides"! Apparently since the mountains are so steep and the rock is so hard, the tree roots do everything they can to get a stronghold, including linking into other trees' root systems. So when one tree falls, usually during a windstorm or earthquake, it takes with it all the trees in the surrounding area. Many of the treeslides seen here occurred during a large earthquake a few months ago (August).
