Grand Canyon Fun Facts Day 1One of the world's natural wonders, the iconic Grand Canyon draws oohs and aahs from visitors perched at the edge of its towering cliffs. Carved by the copper-colored Colorado River, the colorful rock layers record billions of years of history and hide many unique species. Here are seven amazing facts about the Grand Canyon.Though widely considered one of the world's most spectacular canyons, the Grand Canyon is neither the world's longest or deepest gorge.In 1994, the Guinness Book of World Records crowned the Yarlung Tsangpo Grand Canyon in the Himalayas as the world's longest and deepest canyon. Its depth reaches 17,567 feet (5,382 m) and its length 308 miles (496.3 km).It's also not the world's widest canyon Australia wins the prize for the world's widest canyon, with its Capertee Valley edging out the Grand Canyon at a little more than 18 miles (30 km) wide.A canyon plane crash gave rise to the FAA In the 1950s, passenger flights would sometimes detour over the Grand Canyon for a better view. On June 30, 1956, two planes flying from Los Angeles to Chicago, a United Airlines DC-7 and a TWA Constellation, had both requested permission to fly into the Grand Canyon's airspace. The planes collided directly over the canyon, killing everyone on board.

The creamy white Kaibab Limestone forms the surface on which the park's 5 million visitors stand while viewing the canyon. Strong geologic evidence suggests the Colorado River broke out of the west end of the Grand Canyon about five million years ago, and no sooner. But with that constraint, there is heated debate about what the canyon looked like in the millions of years before this anchor.Did the river carve the canyon all at once? Or was there an ancient gorge waiting for the young river, ready to capture its flow? One recent study found some rocks at the western end were eroded and exposed at the surface 70 million years ago. Active debate continues, with scores of research studies ongoing in the canyon.Most of the Grand Canyon consists of rock that is 1 mile deep, 18 miles wide and 277 miles long.There are more than 20 layers of rocks throughout the Grand Canyon.The Grand Canyon is considered to be one of the 7 wonders of the world.
