The badlands at the Zabriskie Point (Death Valley, California, USA) rest upon a mudstone foundation. In the prehistoric lakes of Death Valley, fine grained sediments were deposited to form soft rocks. The clay minerals in the mudstone are shaped like tiny plates, which helps create the layers. The combination of the almost impermeable mudstone and Death Valley’s low rainfall makes plant grow ...[Read More]

The imposing spires, which can reach up to 200m in height, are fluvioglacial deposits that resul ...[Read More]
