There are always surprises in the woods.
The backpackers who filmed this video set up camp at Nellie Lake in the Kaiser Wilderness, CA. While they we siting by the shore the presumably noticed that the waterbugs on the surface of the lake were reacting to their voice. Everytime they shout “Hey” you can watch the bugs move causing a ripple effect across the lake. It’s actually really cool to watch it propagate across the lake in real time.
It’s little things like this that keep us coming back to the wilderness.
