Lately, however, the canyon has also inspired controversy, specifically over its origins.It is generally held by the scientific community that the Grand Canyon formed by the slow erosion of the Colorado River over millions of years. Steve Austin, however, has proposed an entirely different theory on the age and formation of the canyon and wrote a book explaining his theories titled Grand Canyon: Monument to Catastrophe. Austin believes that the canyon was formed extremely rapidly during the period immediately following the global flood of Noah in the biblical book of Genesis. Austin proposed that the canyon is thousands, not millions of years old.
It caused massive sedimentary layering and sorting and fossilizing of the creatures buried therein.
Grand Canyon National Park [see Photo 1] is one of the best places in the world to gain a sense of geologic, or “deep,” time because the canyon exposes a great swath of geologic history.
Rocks exposed in Grand Canyon are truly ancient, ranging from 1840 million years old (m.y.), or 1.84 billion years old (b.y.), to 270 m.y.
This fits into the larger field of Creation Science, in which people try to prove with scientific evidence that the world is only 6,000 years old. Austin's claims and delve into the evidence he uses to support them by examining his book. Austin supports his claim with theories of rapid erosion and Flood deposition of fossils.
He also addresses issues like radiometric dating, in which he attempts to cast doubt on established scientific methods of dating Earth's features.
And today we know through lab experiments and natural disasters (such as the eruption of Mt. Helens) that major layering of rock strata can happen catastrophically in a short period of time.
Young-earth creation geologists have long held that most sedimentary strata resulted from waterborne deposits during Noah’s Flood.
Yet, it is the canyon’s rock walls that allow people to develop their greatest perspective on geologic time, because of these rocks’ immense age, their fossil record, and because these rocks formed in environments far different than those found in northern Arizona today.
With a rock record that spans more than 1500 m.y., Grand Canyon is truly a panoramic view into the geologic past.
When asked to imagine the biggest, deepest, longest canyon one can imagine, an image of the Grand Canyon will often pop into a person's mind.
The Grand Canyon is a site of almost unfathomable grandeur, which inspires awe in anyone who sees it.
The ancient sandstone in the canyon walls contains grains of a phosphate mineral known as apatite -- hosting trace amounts of the radioactive elements uranium and thorium -- which expel helium atoms as they decay, she said.
