After touring the Lewis and Clark Interpretive Center, we enjoyed the day a bit more by visiting the Giant Springs area just up the road.
This water is traveling all the way from the Belt Mountains. It remains underground for the entire trip and I believe there was information indicating it takes 50 years for the water to make the trip (I can't imagine how they know that!)
Anyway, we really enjoyed visiting this area. It was a really beautiful autumn day and we don't really get to spend much time together as a family because we are scattered all across the state. It was a good day.
