Encompassing an estimated 1,218.37 acres (1,904 square miles), the Canyon is capable of holding 1 – 2 quadrillion gallons of water. Really. If you poured all the river water on Earth into the Grand Canyon, it would still only be about half full.

The canyon is 446 kilometres long by an average of 16 kilometres wide and 1.6 kilometres deep, which gives a volume of about 10 million billion (1016) litres. So by simple division Daisy would take about 1.8 million million (1.8 × 1012) years to fill the canyon.
If the Grand Canyon basin was filled, it would fill a lot of canyons, tributaries and river canyons beside the Grand Canyon both upstream and downstream.
Bring your big-boy shovel—and a calculator. Around the world, countries have filled in bodies of water with “reclaimed land.” These range from ornamental uses in Dubai to straightforward waterfront fills. We'd need 1,000 cubic miles of dirt to fill the Grand Canyon.
The Paleozoic Strata contain many fossils that help scientists learn about the geologic history of North America. Most of the fossils are ocean-dwelling creatures, telling us that the area now in the middle of Arizona was once a sea.
With only 150 years of exploration into the Grand Canyon, there is still so much to discover. While it is one of the most sought-after landscapes for geological study in the entire world, we are just beginning to tap the surface of the wonders found within the Grand Canyon.
Right now, there is only about 7 million acre-feet flowing into the Canyon in 2022. But levels are still declining, and we are getting closer to the point where Glen Canyon Dam cannot generate electricity, and potentially even worse, where water really can't safely flow through the dam at all.
Located east of the Philippines, the Mariana Trench is massive. It is 120 times larger than the Grand Canyon and includes millions of acres virtually unknown to humans.
It is also a rich source of fossils, containing a diverse collection of ancient plant and animal remains. Among the most renowned fossils discovered in the Grand Canyon are trilobites, which are extinct marine arthropods that lived over 500 million years ago.
Precipitation falling on the Coconino (South Rim) and Kaibab (North Rim) Plateaus creates Grand Canyon's only native waters - waters derived in place - as they percolate through porous, faulted, and fractured rock units to discharge later as springs and seeps below the canyon's rim.
If you decide to hike in the Canyon, take at least four litres of water for each day and lots of food. You will need a map too. Your mobile phone won't work here, as there is no signal, so make sure your friends and family know exactly where you are and how long you plan to hike.
From the top of the Seven Devils Mountains to the deepest part of the Snake River, Hells Canyon is nearly 8,000 feet deep. That's almost 2,000 feet deeper than the famous Grand Canyon in Arizona.
Nestled along the Idaho and Oregon border lies one of the greatest natural wonders in North America: Hells Canyon. Carved by the Snake River, the gorge is ten miles wide and plunges 7,913 feet. That's 2,000 feet deeper than the Grand Canyon – making it the deepest river gorge in North America.
Only a mile a deep, Grand Canyon is not the deepest in the world. For example, the Washington's Colombia River Gorge measures over a mile and a half in depth. Though not the deepest, Grand Canyon remains an incredibly impressive natural landform.
Though they can scarcely be seen from the viewing areas along the rim, mines thrived within the canyon in the early 1900s, as camps extracted copper and gold from more than 40 sites.
Towering 4,000 feet above the Grand Canyon is the $30-million Skywalk, a horseshoe-shaped glass walkway. Built in 2007, the Skywalk gives you the feeling you are walking on air.
