Badlands National Park - Is this the Earth?

We had to drive back to Sioux Falls, SD, today from the western side
of South Dakota. On the way, we drove through part of the Badlands
National Park.

The Badlands are very cool. It does look like another planet. I felt
like I had just beamed down from the USS Enterprise on a mission with
Mr. Spock and Captain Kirk.

We also stopped at the Visitor's Center and watched a film about the
history if the area. I did not know the whole area was once covered
with shallow water. It has changed a bit since then.
