The rich hue of the Yellow Mounds paleosols

The yellow and red layers in the badlands formations are fossilized soils, called paleosols. Fossil root traces, burrows, and animal bones found within the soils provide scientists with evidence of environmental and climatic changes that occurred in the badlands over time.
