Geological Feature of Grand Canyon - Rock Solid

If you are wondering what geological feature of Grand Canyon is the most significant, that would be hard to answer. Many scientific elements have come together over millions of years to form what we now know as the vast wonder of the Grand Canyon. Various depths, crevices and inner layers are comprised of different metals and minerals.

Erosion and corrosion are two main elements that have helped to create a specific geological feature of Grand Canyon. Harsh weather conditions, the Colorado River, and human and animal presence are just some of the things that have given shape to the canyon.

Over time, volcanic activity from millions of years ago had divided the canyon into various pieces, and what has remained are crystalline rocks formed during the Proterozoic Era. What had been left is hardened magma, and an immense amount of granite.

During the Paleozoic Era deposition occurred, laying down sedimentary rock. Layers of sandstone, shale and limestone are thousands of feet thick, making parts of the canyon walls extremely delicate, and very dangerous to climb.

But to analyze the oldest known rocks at the Grand Canyon, one must scale down to the bottom where the Vishnu Group can be found. Though very little is known about their survival rate and precise age, these are comprised of clay mixed with sand and ash. Furthermore, much of the bottom portion of this geological feature of Grand Canyon is actually ‘alive’, and to continuously break this soil can release many different types of bacteria.

As with any ancient rock formation, there are a great many opportunities to find fossils in many parts of the walls and floor. Fish, bird and lizard fossils, with calcium deposits are scattered about. And since the Grand Canyon is extremely dense, archaeologists have a heck of a time digging in order to determine if dinosaurs roamed in this part of the world.

But one thing is for sure: any geological feature of Grand Canyon will surely have a history that may be traced back millions, and sometimes even billions, of years. You are not only going to view a wonderful U.S. landmark, but a scientific wonder full of biology, chemistry and mystery.
