These rocks tell a story, a profound one no doubt, but also one that this non-geologist is incapable of fully comprehending. But I do know a few things, and with that bit of knowledge and the time to observe, I can report that there is a lot to think about in places like this and, for that matter, the entirety of Death Valley National Park. A difference between this landscape and most others with which I’m familiar is that here it is almost entirely exposed rather than being hidden underneath forests and snow.

As I understand it, the course of many of the rocks here is sedimentary — they were formed under ancient seas. (Portions of the valley were submerged much more recently, and that shorter tale is visible, too, in places.) Those sediments sometimes captured creatures that became fossilized, as we see in the black spots in the rocks of this photograph. Then various geological forces lifted, tilted, fractured, and contorted these layers over a vast span of time. In many places in the park the strata are inclined upward as they progress to the west. Here one of the inclined rock bands contains colors that are the exception rather than the rule in this national park.
