How old is it?
No one really knows how old the Grand Canyon is. While it was earlier thought to be six million years old, around the time the Colorado river cut through the landscape, many believe the Canyon could date back as far as 70 million years. This thought came to the fore after a study released in the early 2010s suggested some of the rocks in the Canyon may have been eroded and exposed at the surface millions of years ago. However, the debate, on how old the Grand Canyon actually is, goes on.
Not the deepest canyon
Though it is one of the most popular gorges, and a natural wonder of the world, the Grand Canyon is not the deepest or the longest gorge. The average depth of the Canyon is 1.6 km and it stretches nearly 446 km. However, the Guinness Book of World Records states that the Yarlung Tsangpo Grand Canyon in the Himalayas is the world’s longest and deepest canyon with its maximum depth reaching about 5,382 m and the canyon stretching nearly 496.3 km.
Experience different weather conditions
With an elevation spanning 2000 feet to 8000 feet, one can experience a variety of weather conditions at the Grand Canyon. With every 1000-feet loss in elevation at the Canyon, the temperature increases by 5.5 degrees Fahrenheit.
Hidden Caves
It is estimated that there are nearly 1,000 caves spread across the Grand Canyon. However, only 335 of them have been recorded and explored so far. Of the 335, only one cave, the Cave of the Domes on Horseshoe Mesa, is open to the public.
Beware the rock squirrel
The Grand Canyon is home to a large array of wildlife from the bighorn sheep and the Gila monster, to the California condor and Ridgway’s rail. But the most dangerous animal at the Canyon is the rock squirrel! Every year dozens of visitors to the Canyon are bitten by these animals when they try to feed them. Hence, one can find signs around the park asking people not to feed animals.
