Here are a few pics from our first day: Talking Rocks Cavern.

We had some time to kill before our cave tour, so we hiked up to a lookout tower.

Here are some rocks that the kids climbed up along the way.

Here we are at the top of the tower overlooking the Ozark Mountains.

I love this pic! They are inside an air bubble in the cave where it washed out. It was a little room (sort-of).
Stalactites meeting stalagmites.

This was a really cool part of the cave. The picture, of course, didn't do it justice. At the bottom of the picture there is a formation looking like angel wings. The guide said that the angel was bowing to something and they always wondered why. One day, someone pointed out what seems to be a formation that looks like a cross higher up on the cave wall. It really was pretty cool, but is hard to see. My camera angle wasn't great either. I have traced it in red in the picture below the original.
