One of my favorite days so far. We went on a geology walk to learn about all the rocks of the park and the formation of the rivers.

 There was a rock slide and the boulder behind me landed in the crater that I'm standing in and then rolled.

This is the coolest part of the river. Look closely at the different colors! One river is a glacier river (the chocolate milk) has a lot of sediment.  The other river is greenish clear and is just a mountain creek.
