Bending rock sounds like the feat of a superhero. But this incredible achievement really occurred in the earth’s past. There are many places around the world where thick layers of rock are folded, sometimes at angles of 90°! One prominent example is the Carbon Canyon Fold.
The Carbon Canyon Fold is located in a side canyon adjacent to Grand Canyon itself. The layers making up the fold are a sequence of sandstone, siltstone/claystone, and limestone. Together, they make up the Tonto Group. In most places, the Tonto Group layers are just as horizontal as when they were deposited. But this is not the case with the Carbon Canyon Fold. How were these layers warped at such an unusual angle?
Conventional wisdom tells us that the oldest layers of the Tonto Group layers are approximately 525 million years old. Geologists think the uplift that folded the Tonto Group layers started between 70 and 50 million years ago. It was not complete until a mere five million years ago.
This model is problematic, however. There is no known mechanism by which the Tonto Group could have remained wet and pliable for 465 million years! The folded nature of this rock unit is incredible evidence of their relative youth. Those who believe these layers were formed over vast eons of time proposed other ideas to explain how the layers were folded long after hardening into rock.
Metamorphism is a process capable of making solid rock pliable again for folding. This can occur when the rock experiences extreme heat and pressure far beneath the earth’s surface. However, this cannot explain the folded layers seen in the Tonto Group. Metamorphism completely alters a rock’s mineral makeup. For example, such heat and pressure turn sandstone into quartzite. Claystone turns into a schist. Meanwhile, limestone turns into marble. If metamorphism were responsible for folding the Carbon Canyon Fold, evidence for this process should be obvious.
The best explanation for the warped nature of the Carbon Canyon Fold does appear to be that the process of folding occurred in the not-too-distant past. Most young-earth geologists think the uplift that caused the folding occurred over a period of time lasting just hundreds, and not millions, of years. If hundreds of millions of years passed between the formation of the Tonto Group layers and their uplift, the Carbon Canyon Fold should be a jumble of shattered rock fragments. The fact that they are not stands as testimony to their relative youth.
