What was Monument Valley made with?

Answered by Willian Lymon

Monument Valley, oh how I remember standing in awe of its majestic beauty. The towering sandstone formations that dominate the landscape are truly a sight to behold. But have you ever wondered how these incredible structures came to be?

Well, let me take you back in time to the Permian period, around 300 million years ago. Back then, this area was covered by a vast shallow sea. Over millions of years, sediments, including sand, silt, and clay, gradually accumulated on the seafloor. As the currents carried these materials, they settled and layered upon one another, forming what would become the foundation of Monument Valley.

The primary component of Monument Valley is sandstone, which is a type of sedimentary rock. Sand grains, composed mainly of quartz, were deposited in layers over time. The weight of the overlying sediments and the chemical reactions between the minerals caused the sand grains to bind together, forming solid rock.

Tectonic forces, those powerful movements of the Earth’s crust, played a significant role in shaping Monument Valley. As the continents shifted and collided, the region was gradually uplifted, eventually rising above the waterline. This uplift created a plateau, exposing the once submerged seafloor to the forces of erosion.

Over the next millions of years, wind and water relentlessly carved away at the exposed sandstone, sculpting the iconic buttes, mesas, and spires that we see today. The abrasive action of wind-blown sand particles and the erosive power of intermittent rainfall gradually shaped the soft sandstone, creating the breathtaking geological formations that have become synonymous with Monument Valley.

It’s truly remarkable to think about the immense forces and the passage of time that have shaped this land. Standing amidst the towering sandstone formations, one can’t help but feel a sense of connection to the ancient past. The layers of sandstone tell a story of millions of years of geological history, a testament to the ever-changing nature of our planet.

So, the next time you find yourself in Monument Valley, take a moment to appreciate the incredible journey that these rocks have undertaken. From their humble beginnings on a seafloor to their grandeur atop a plateau, the sandstone formations of Monument Valley are a testament to the enduring power of nature.
