|Camping on the Boulder River|
|Dogs on dash|
With an extra day scheduled for exploring, we drove south along the river through beautiful ranch lands for about 25 miles and ended up, more or less by accident, at Natural Bridge State Park. This is a nice little park built around a landmark where, over hundreds of thousands of years, the Boulder River gradually eroded away a sandstone wall until it finally broke through and created a span crossing the river. And here it is...

more of a natural tunnel. And it isn't big enough to handle the water volume in the spring, so for a couple of months a year the water partially goes back to flowing down the old river bed over the top of the tunnel. But as time and the elements continue to work, they say that the tunnel will gradually enlarge and will eventually form a new bridge. That's why they haven't changed the name. Why go to the trouble of changing all the signs when you're just going to have to change them back in half a million years? Now that's what I call planning ahead.
There were a couple of interesting displays. We always like to see collections of old medical tools. It makes me long for
Adjacent to the museum building was an old schoolhouse, which we ignored, and an old Norwegian style storage building from the last century. Much of the far northern Midwest was settled by Scandinavians who apparently have an inexplicable fondness for blisteringly cold winters.
Having fulfilled our culture educational requirement for the week, we drove back to our campground to enjoy our riverfront lodgings before packing up in the morning to continue our journey to South Dakota.
