There is also an ice-cold stream that runs through the center of the gorge, the source of which is an underground river. The kids were brave enough to swim through some small pools of water that are fed by a gorgeous waterfall.
We ended this journey with a family fossil hunt. We were lucky to find a cool fossil and some crystals. It was a very fun, relaxing, interesting afternoon!
