I was eight years old when my family drove through the Bad Lands on our way back from California. The place impressed me as a kid. Sixty years later, I was wondering if I had remembered it accurately. I did. It was almost exactly as I expected, and it was still impressive. The only thing I didn’t remember was all the grassland that surrounded the Park. That made for a fascinating boundary where the lush grasses met the stark formations of the Bad Lands.
It turns out that the eroding soil that is the Bad Lands is mostly volcanic ash. Each thin layer of ash represented thousands of years of ash deposits.
Of course, South Dakota was once a shallow sea. So, let’s see, New Mexico was once a shallow sea. Utah was once a shallow sea. This shallow sea business is especially interesting because each map we saw depicting this shallow sea did not include the other areas. For instance, Utah’s shallow sea map did not show South Dakota under water and visa versa. I guess the shallow sea roamed around a bit taking in the sights just like we are.
We hiked five different short, but fun trails, adding up to just 3 miles of walking. One trail, however, the Saddle Trail, was pretty much straight up, so we are tripling that half-mile, making our total for the day to be 4 miles.
In some areas the formations were pure white compressed ash. Most formations, however had red stripes. One area was tri-colored with yellow added to the whites and reds. The plaque stated that the red and yellow coloration was just oxidations, no fancy metals or minerals. Oxidations of what? The plaque didn’t elaborate.
