Fiery Gizzard was the best activity I did so far! We hiked with Dr. Evans down a really steep trail with lots of rocks. Along the way he told us about different trees like the fungus hemlocks and rotting logs. All through the trail we could hear the stream. Finally after a good bit of hiking, we reached a deep water hole with a waterfall flowing into it. The water was a lot clearer than Lake Cheston, but also colder. It was fun to go underneath the waterfall. Later, after we all cooled down in the water, we dried off and started the accent up the mountain.
