What Is Grand Canyon Famous For – Why Is The Grand Canyon So Famous?

  • The Grand Canyon is famous for its richest archeological history, numerous geologic features, and considerable fossil records.
  • It is one of the world’s most studied landscapes.
  • It is well-known for its finest and eye-catching sceneries.

What is the best month to visit the Grand Canyon?

  • The best months to visit the Grand Canyon are from March to May and from September to November.
  • During these months, the daytime is cool and there are no hordes of tourists. 
  • The summer season is the peak season of tourists. If someone decides to visit in summer, he would face huge crowds of tourists and limited lodging availability.

How dangerous is the Grand Canyon?

  • The Grand Canyon is dangerous because of the hostile landscape and harsh weather.
  • Visitors often underestimate the wilderness of the Canyon, which leads to life-threatening situations. 
  • The heat and extremely dry air of the desert quickly evaporate the sweat. So the hikers have a high risk of dehydration, heat exhaustion, and heatstroke. Since 2010, about 42 people have died of such conditions.
  • Falling accidents are another danger at the Canyon. Visitors are advised to not climb fences and take extreme care near the edges. Since 2010, 27 people have died from fall accidents.
  • The Grand Canyon National Park is considered the most dangerous National Park in the United States, where the number of total deaths since 2010 is 134.

What should you not do at the Grand Canyon?

  • You should not do the following things at the Grand Canyon:
  • Do not arrive at the peak season (Summer and Spring), otherwise, you would face a horde of visitors. Because millions of tourists visit the Grand Canyon each year.
  • Do not neglect to bring enough water and stay hydrated. A hiker needs a gallon (4 liters) of water per day to feel best, as he/she is crossing a high desert. 
  • Do not underestimate the wilderness and altitude of the Canyon. When a visitor arrives at the South Rim, he/she has reached an elevation of 7,000 feet. While the altitude of the North Rim is 8,000 feet.
  • Do not forget to pack for the changing weather conditions. Weather at the Canyon can suddenly change from warm to windy or raining or even snowing. 
  • Do not underestimate the sun and take sunscreen, hat, and lip balm, as the sun can be brutal suddenly.
  • Do not get close to the Rim and do not climb fences. The mesmerizing views of the Canyon cause some people to lose track and forget where they are. So be careful, as one false step can take your precious life.

Why are there no fish in the Grand Canyon?

  • A wide variety of fish was once found in the Colorado River, which is running through the Grand Canyon.
  • However, the aquatic habitat of the Colorado River is variable and extremely challenging for fish. For example, the summer temperature is warm while the winter temperature is near-freezing, very large floods occur in the spring, and the silt load is heavy.
  • As a result, most of the fish species did not endure the challenging habitat and disappeared. So, only eight fish species were native to the Canyon.
  • These are:
    1. Humpback chub 
    2. Razorback sucker 
    3. Bluehead sucker 
    4. Flannelmouth sucker 
    5. Speckled dace 
    6. Colorado pikeminnow (extirpated)
    7. Roundtail chub (extirpated)
    8. Bonytail (extirpated)

Did The Colorado River Create The Grand Canyon?

  • Yes, the Colorado River created the Grand Canyon.

What Is The Geology Of The Grand Canyon – The Grand Canyon Geology

  • The clear horizontal layers of different rocks in the Grand Canyon provide information about how, where, and when these rocks were deposited.
  • As three main types of rocks can be also found in the Grand Canyon. These are:
    1. Igneous Rocks, which are cooled lava (molten rocks expelled through the ground) or magma (molten rocks found underground). Basalt and Granite are two types of igneous rocks. Basalt is formed from the cooling of the lava and is known as extrusive igneous rock. While granite is formed from the cooling of magma and is called intrusive igneous rock.
    2. Sedimentary rocks are formed by the accumulation of small pieces of mud and sand in layers.
    3. Metamorphic rocks are formed when igneous or sedimentary rocks are subjected to high temperature or pressure.

The Grand Canyon facts for kids

  • There are three major sets of rock layers in the Grand Canyon that are grouped on the basis of their position and common composition. These are:
  • Metamorphic Basement Rocks 
    • The oldest rocks in the Grand Canyon are mostly metamorphic with igneous intrusions (igneous intrusion means lava or magma cooled over previously formed rocks).  
    • These rocks are found at the bottom of the Canyon.
    • Here, these rocks (the intrusive rocks) are known as Zoroaster granite.
    • This set of rocks (a combination of the old igneous and metamorphic rocks found at this position) is named Vishnu Basement Rocks. These rocks are mostly schist (metamorphic) with granite (igneous) and have visible crystals. 
    • This set of rocks is about 1.7 billion years old and belongs to the Proterozoic era.
    • Powell named this portion of exposed rock as “The Granite Gorge” during his expedition.
  • The Precambrian Grand Canyon Supergroup
    • The Precambrian Grand Canyon Supergroup is the middle set of rocks at the Grand Canyon.
    • This is mostly composed of mudstone and sandstone, both are sedimentary type rocks with some igneous rock regions.
    • This rock-set belongs to the late Proterozoic era and formed slightly late from the Metamorphic Basement Rocks.
    • The rock layers in this portion have been tilted, while other rocks are horizontal above these rocks. This is called an angular unconformity. 
    • This then led to “The Great Unconformity”  when the top part of these sediment layers eroded.
  • The Paleozoic Strata 
    • This rock set is composed of sedimentary rocks that are primarily sandstones.
    • The typical reddish layers of the Grand Canyon that we often see in the images are mostly made up of this rock set.
    • This set lays above the Great Unconformity and has widespread fossils. 
    • This rock-set formed much later than the other rock layers of the Canyon.
    • Scientist and explorer John Wasley Powell described the above sets of rocks for the first time during his expedition to the Canyon in the late 1860s and early 1870s.

Grand Canyon History FactsWhat’s The History Of The Grand Canyon?

  • The oldest rocks found at the bottom of the Canyon are estimated to be about 1.7 to 1.8 billion years old.
  • Above these rocks is laying another ancient layer of sandstones, limestones, and shales that are estimated to be more than 540 million years old.
  • Overlaying the top of this layer is another layer or set of rocks (the Paleozoic Strata) with the typical reddish color that we see in photos. The depositional period of this layer is estimated to be extending over 300 million years.
  • The carving process of the mile-deep Grand Canyon through the Colorado River is relatively recent in the geologic history of the Canyon. It started around six million years ago when the river started flowing its present course. 
  • However, some recent studies reveal that the carving process may have started around 70 million years ago.

What Are The Oldest Rocks In The Grand Canyon?

  • The oldest rocks in the Grand Canyon are the Vishnu Basement Rocks, which are estimated to be about 1.75 billion years old.
