A couple of miles north of Badwater Basin, is the Natural Bridge Canyon. There is a short, but really bumpy drive from the highway to the start of the trail.
This is where the trail starts. I was amazed by all the colors in the mountains. (I was planning to go to the Artists Drive, but the road was for some reason closed).

Walking up to the natural bridge was several waterfalls carved in the side of the canyon.
People obviously have had fun here creating small rock towers. There were plenty of them all throughout the valley.
After about 15 minutes walk up the canyon was the natural bridge, with me underneath. (I had forgotten my radio-remote in the car, so had to use the 10 second timer and run to get the photo :-)). This photo should give you some impression of the size of the bridge.
The light conditions were difficult, with the sun shining on parts of the canyon, and other parts in shade. So in addition to adding contrast, I’ve increased the “shadows” and reduced the “Highlights” and “Whites” in the photo.

The rock towers might be cairns. They are used to mark trails where the trail can be hard to make out; where the ground is rocky.
