When we're in the neighborhood, we just can't resist stopping at Kitch-iti-kipi, also known as The Big Spring. We don't usually stay for long, but it's so interesting we just have to stop.
The kids love "driving" the raft (A.K.A. turning the wheel to pull the raft across the spring,) and, of course,
watching the trout swim around beneath them. Something like 10,000 gallons of water feed into the spring each second, so watching the sand erupt like little volcanoes on the bottom of the spring is pretty cool, too.
The hardest part for Allen and K was not being able run back to the car to get their fishing poles. So many trout, but no fishing is allowed in the spring. Sigh.
I'm going to look into taking my class there this fall for a field trip. They have a naturalist on staff who may be able to put a program together for us, and I'd be willing to bet that not many of my students have ever been there.
