Can all the humans fit in the Grand Canyon?
And, not surprisingly, the human pile would only comprise a small portion of the Grand Canyon. In fact, a model of every human that has ever lived showed that an estimated 106 billion people still wouldn't cover the Grand Canyon entirely.
We'd need 1,000 cubic miles of dirt to fill the Grand Canyon.
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 you poured all the river water on Earth into the Grand Canyon, it would still only be about half full. It's so big that you could fit the entire population of the planet inside of it and still have room!
There's a town in the Grand Canyon
Supai Village is located at the base of the Grand Canyon within the Havasupai Indian Reservation. Inaccessible by road and with a population of just 208, it is the most remote community in the lower 48 states, and is the only place where mail is still delivered by pack mule.

Despite these strategically located private in-holdings, the vast majority of the Grand Canyon is owned by the federal government, held in trust for the American people and managed by a varied collection of federal agencies. Indian reservations, state land, and private land surround these federal lands.
Most of us would argue that our state's greatest natural wonder is priceless and worth more than all the money in the world. But according to a January 2017 action by the U.S. Congress, the Grand Canyon is a worthless hole in the ground — its value is exactly $0.
The Grand Canyon is bigger than the state of Rhode Island.
The Grand Canyon is a mile deep, 277 miles long and 18 miles wide.
It is 6,000 feet deep at its deepest point and 18 miles at its widest. However, the significance of Grand Canyon is not limited to its geology.
What is the deepest depth of the Grand Canyon?
The deepest part of Grand Canyon is about 6,000 feet (1,829 meters) deep. The average depth is 1 mile or 5,280 feet (1,609 meters).
Called the Mariana Trench, the underwater canyon descends 35,827 feet (10,920 meters) — the Grand Canyon only averages about 4,000 feet (1,200 meters) in depth.

The rocks deep in the canyon floor and below the falls are full of limestone deposits known as travertine. When the travertine-rich spring water meets the air, a chemical reaction occurs and calcium carbonate – the same stuff in chalk – in the water reflects the sunlight above to appear turquoise.
Feeding, touching, teasing, or intentionally disturbing wildlife is prohibited. Throwing or rolling rocks or other items down hillsides or mountainsides, into valleys or canyons, or inside caves is prohibited.
You can travel to the Bottom of the Grand Canyon by selecting any inner-canyon trails, hiking down by yourself, using a mule that may cost up to $500, or more adventurous tourists can raft down in the Colorado River to reach the Bottom of the Canyon.
Because of this, many visitors to the Grand Canyon National Park ask the question: "Are there any bears here?" The answer is "No", except for an occasional transient along the South Rim on its way through the park to another region.
Although this dissolved inorganic material causes the water to be slightly cloudy, the dissolved material is well below maximum contaminate levels established by the Environmental Protection Agency and is not harmful to health.
Are There Bathrooms in the Canyon? All three of the camping sites and Phantom Ranch have bathrooms, however, be prepared with your own toilet paper and waterless soap.
The Grand Canyon averages 12 deaths per year, two or three of which come from falls.
From 1958 to September 2021, there were only 29 open cold cases for individuals who went missing at a national park. Of these, Grand Canyon and Yosemite make up over half – 11 from Yosemite and 5 from Grand Canyon. This works out to less than 1 person every 5 years.
What will happen if they shout into the canyon?
If you shout into a well or a canyon, the echo comes back a moment later. The echo occurs because some of the sound waves in your shout reflect off of a surface (either the water at the bottom of the well or the canyon wall on the far side) and travel back to your ears.
It took a moment to parse out with students that in fact China did not buy the Grand Canyon, that a google search of the actual news clearly bore that out and that the site they located was satire.
According to a new National Park Service report, over 4.5 million people visited Grand Canyon National Park in 2021, shelling out $710 million in local gateway communities. All that spending supported over 9,300 jobs, $324 million in labor income, and $945 million in economic output.
Tourism to Grand Canyon National Park contributed $710 million to local economy in 2021. A new National Park Service (NPS) report shows that 4.5 million visitors to Grand Canyon National Park in 2021 spent an estimated $710 million in gateway regions near the park.
The Canyon's Wonderous Geology Will Remain
There's different flora, there's different fauna, the river looks different, and instead of these rocky hillslopes, they look a little more like ones we normally see in Colorado instead of Arizona? I think that it would just take 10,000 to 20,000 years, max.
Since you were wondering, yes, people live inside the Grand Canyon. Supai Village, the capital of the Havasupai Indian Reservation, boasts a population of a couple of hundred residents.
The Havasupai, also known as the “People of the Blue-Green Water,” live on 3 million acres near the South Rim. The arrival of the Havasupai is set at around A.D. 1300, and they are known to be the only permanent, continuous inhabitants of the Grand Canyon.
Temperatures usually vary by 20 ºF (11 ºC) between the top and the bottom. Summer (June – August) – Temperatures often exceed 100 ºF (38 ºC) at the bottom of the canyon.
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.
It will take most hikers between 4 and 5 hours to get to the campground on either trail. Oddly enough, very few people ask how long the return hike will take. The return hike may take twice as long, though 7 to 8 hours seems to be average.
How long would it take to raft the entire Grand Canyon?
The fastest way to raft the Grand Canyon is with motorized boats that can cover the distance in about 7 days, depending on how many stops you make. For those in oar boats, plan on between 15-21 days.
The Grand Canyon has an estimated volume of 40 billion cubic meters. 1 grain of sand occupies approximately 1 cubic milimeter. Thus, the Grand Canyon could hold roughly 4e19 grains of sand.
The Canyon Will Change Its “Clothes”
As it becomes warmer and drier, you'll see vegetation that is more classic to those environments: piñon-juniper will shift more into just juniper and maybe some grasses, which is the vegetation zone that falls below it.
The Grand Canyon is 277 miles long.
The Colorado River keeps going, along the border with Nevada, then the border of California, briefly the border with Mexico and down through Mexico to the Gulf of California. You might be surprised to learn that there are longer (and deeper) canyons on Earth, however.
The river's average width is 300 feet across, although it narrows to only 76 feet wide at mile 135, where the river, 85 feet deep, is also at its deepest. On average, the Colorado River within the Grand Canyon is 40 feet deep.
Restrictions: 7 or 10 year age limit, depending on trip. 200 lb/94 kg or 220 lb/102 kg weight limit, depending on trip.
Humanity's appetite for sand could soar 45 per cent within four decades, according to researchers who say unchecked consumption risks environmental damage and shortages of a key material for urban expansion.
Each grain is 1/1,000th of a foot wide, so it takes 1,000 x 1,000 or about 1 million grains of sand to cover just 1 square foot. That's just a thin layer of single grains…if you want a few inches of sand, you need hundreds of layers, giving us over a billion grains for a grown-up!
Walls, buildings, cement, concrete and glass — sand forms the framework for most of our physical world. But as our demand for it continues to grow, we're quickly running out of this precious natural resource.
A number of key external threats including over flights, uranium mining, bison management, and concerns with management of Glen Canyon Dam as well as problems of water management if drought occurs or water extraction due to development increases could be difficult to manage.
Was Grand Canyon an ocean?
The composition (sandstone) and presence of stromatolites indicate that this area was previously a very shallow sea. The rock layers in the Grand Canyon Supergroup have been tilted, whereas the other rocks above this set are horizontal.
Phantom Ranch, at the bottom of the Grand Canyon, is a popular destination for both hikers and mule riders. Overnight hiker dormitories and cabins can be reserved and meals are available for purchase. Advance reservations for meals and lodging at Phantom Ranch are required.
About 12 deaths happen each year at the Grand Canyon, including from natural causes, medical problems, suicide, heat, drowning and traffic crashes. On average, two to three deaths per year are from falls over the rim, park spokeswoman Kirby-Lynn Shedlowski says.
Grand Canyon, Arizona
The deepest part of Grand Canyon is about 6,000 feet (1,829 meters) deep. The average depth is 1 mile or 5,280 feet (1,609 meters).
