Badlands national park, South Dakota, USA
by Iain Willis
I took this picture of my brother Paul as he stood on the edge of the badlands national park. We were doing a road-trip from Chicago to San Francisco during July. It was pretty overcast but the sun had just lit up the landscape.
It's a great example of the geomorphology that has eroded this strange landscape.
