Badlands Yellow Mounds

When the black hills were formed in South Dakota the ancient sea drained away. Once exposed to air, the black ocean mud was weathered into a yellow soil known as the yellow mounds. Tropical plants began to grow. Today many fossils are found in the yellow mounds.

I took these shots on a somewhat cloudy day which diffused the normally harsh afternoon light and added to the soft colours in the hills.
