Every year, millions of people travel to Utah to take in the beautiful and peaceful scenery in Zion National Park. According to a new study, however, the geographic stunner was formed by a massive prehistoric landslide that was far from tranquil.
The study, published Thursday in the Geological Society of America, said the park’s flat valley floor owes its creation to the collapse of a wall of Navajo Sandstone that was almost 900 miles high. Weak layers in the underlying Kayenta Formation sent debris shooting across the canyon at speeds that likely reached 90 miles per second. It's believed that the event took place around 4,800 years ago.
"The ancient Zion landslide would cover New York City's Central Park with 275 feet of debris," Jeff Moore, senior author of the study, told Phys.org. "And you would need 90 times the volume of concrete in Hoover Dam to recreate the mountainside that failed." The massive slide blocked Zion Canyon over a distance of about two miles, damming what is now the Virgin River and forming Sentinel Lake, which lasted for 700 years before dissipating, according to the study. Remaining clay beds and fossil mollusks preserved throughout the canyon provide evidence of a time when the lake occupied the area before it became filled with sediment.
The landslide was first documented in a scientific paper in 1945, but this new study gives more details about when it took place, as well as insight into its characteristics. According to the study, the researchers took samples from 12 boulders across the rock avalanche deposit to test using surface exposure dating. They found that boulders across the surface of the slide had deposited simultaneously, which indicates the slide was a single, massive event.

Yup. A wall 4,720,000 feet tall. By way of comparison, the summit of Mt. Everest is 29,035 feet above sea level.
/most journalists are morons
The thing coming down at Mach 360 would certainly get your attention.Even on the other side of the planet.
I know a few janitors. They aren’t near this stupid.
I would bet that they don’t know what they meant.Probably they get paid by the word.
A 900 mile tall wall of anything coming down at Mach 360+ anywhere on the planet would get my attention. For about a second. Then I’d be dead as would everyone else. That would be an extinction level event.
Against, most journalists are morons.
Can you imagine the sonic boom(s), as the avalanche reached Mach-1, 2, 3 thru 6./Sarc.
Probably just working from an abbreviated ‘m’ which could also mean meters ???
Mach 425
60 mph is 88 ft/sec ... 90 miles per sec? LOL went into orbit did it?
Primary Seismic Waves (longitudinal compression) travel at ~5,000 m/sec in granite or about 3 miles per second. Yet Miss Ada claims this mass of stuff was moving 30 times faster than a P-Wave. Sure, Ada.
Ada, are you positive this didn't occur 4.8 Trillion years ago? Or maybe 4.8 microseconds ago?
Methinks Ada failed Fifth Grade science class and then decided to become a "journalist." The stupidity doesn't get much stronger that this. What a dunce. Wear this hat in the corner for the next month, Ada.
...and these are the people who want us to believe in the Global Warming Fairytale.
They likely mistook m to mean miles, when it means meters. At that, the “wall” would have been nearly 3000 ft and spread at about 200mph.

What is the terminal velocity of a rock falling from 900 miles up?
90 miles a second seems to unattainable speed. meteors travel at about 22,000 to 30,000 mph if I remember correctly.
Debris moving at 90 miles a second? That’s 324 000 miles per hour.
That takes a lot more faith to believe than does Noah’s flood.
Maybe they get paid by the mile.
Nowhere is
There science to be found
Among those who are
mathematical clowns.
Thanks BenLurkin, the ‘900 miles’ figure must be a typo. Good topic for the Catastrophism list.

We are jumping to light speed Chuy. Watch those rocks.
LOL,the writer should be banned from getting within armslength of a keyboard.
A wall 900 miles high would be 3 or 4 times higher than the orbit of the International Space Station. Instead of the collapse of the wall exceeding 300,000+ miles an hour down, the wall would remain in orbit and become a second Moon.
Proof readers and mid-level journalists are losing jobs faster than $15 an hour McDonalds employees.
