On steep trails descending the mountains that follow streams and rivers, most of which lead into a lake near the base of the mountains. This is Arrowhead Lake, it's named for it similar shape to a very sharp chipped indian arrowhead that you can see from up high on the mountain trails. There are many twists and turns around this massive lake. It spreads so vast that the treeline from one side looks like a blur of dark green and is practically impossible to see on the clearest of days. There are some lovely lagoons with clear pooling water for a nice refresher after a long arduous trip down the mountain side.
