Fun Facts About the Grand Canyon

One of the most awe inspiring natural wonders in the world is located in northwestern Arizona. The Grand Canyon is an experience you have to see in person to appreciate. It's an utterly amazing place to visit.

Fun Facts About the Grand Canyon


The Grand Canyon is considered one of the Seven Wonders of the World. The canyon is up to 18 miles wide, 277 miles long and about a mile deep. Scientists estimate it took three to six million years to form. It's common knowledge that the canyon was formed by the Colorado River. This is what children have been taught in school for many years. However, scientists now believe the canyon was formed from a number of different processes that include:

  • The Colorado River
  • Erosion from water ice and wind
  • Volcanism
  • Continental drift
  • Slight variations in the Earth's orbit
  • Giant anomalous structure underneath the Colorado Plateau

One of the most recent discoveries according to Livescience, is that of an anomalously cold, dense region, more than 120 miles deep, sinking into the earth, located in the lithosphere under the Grand Canyon and much of the Colorado Plateau. It appears the anomaly is pulling off the lower part of the crust above it, which could account for much of the unusual geology in and around the Grand Canyon.

Wildlife and Ecosystems

The Grand Canyon is home to a wide variety of plants and animals. The canyon is comprised of different ecosystems, such as:

  • Cave systems
  • Forests
  • Prairies and grasslands
  • Rivers and streams
  • Deserts

The Canyon also runs through part of the Havasupai Reservation. According to, the diverse wildlife in the Canyon includes different species of:

  • Plants -1500
  • Birds - 355
  • Mammals -89
  • Reptiles - 47
  • Amphibians -9
  • Fish - 17

There are also waterfalls in the Grand Canyon. The canyon is always changing and in 2008, a significant flash flood caused the extinction of a well-known waterfall called Navajo Falls. However, the flood also created two new waterfalls, which are unofficially named Rock Falls and New Navajo Falls. The other three waterfalls are:

  • Havasu Falls
  • Mooney Falls
  • Beaver Falls
