The dead trees on top really set the mood. I don't like the whole sign and road thing, though. The photographer should've gotten a different picture.

the sandstone is between 2 harder limesto ne layers which helps explain how the falls move up the river. The U has and underground building they created in the St. Peter layerby using high pressure water hoses and pumps. It stays 50 deg yr-round so is very energy efficient.

the james hill house is cool. If you get the tour you can see secret passages and huge halls and even the newest things in his time.

The St. Peter Sandstone and the town of St. Peter were both named after the St. Peter River, which was the original name of the present Minnesota River. But if you search St. Peter Sandstone online you WILL find lots of amazing images, because it turns up in a bunch of states and State Parks.

The big ones are closed off because they're dangerous. They collapse, fill with carbon monoxide, etc. But there are little ones all over the place. Take a walk in the section of the park accessible from Point Douglas Road. There are some immediately north of the big trail.
