Witnessing Erosion in Action!
A small part of the sandstone cliff breaks and falls into the Colorado River in the natural process of erosion.
The sandstone in the Grand Canyon area is believed to have been deposited between 200 million and 2 billion years ago in what would have been warm, shallow seas.
Plate tectonics then led to the uplifting of the whole region into the Colorado Plateau approx 2 miles high, some of which is slowly being eroded away here.
Nature continues the process of Creative Destruction, turning mountains into mud, into beds of sandstone, into raised plateaus and slowly back into mud.
This, combined with magma from deep within the earth, occasionally leads to conditions that are favorable for mineralization, giving us the beautiful crystals and gems that we love and cherish…
