Most of eastern Washington State is either farmland or mountains, but then there are large swaths of the landscape where all you can see is barren bedrock and strange rocky land formations. The early settlers in eastern Washington referred to these areas as scablands because they were not suitable for farming.
Where did the water for Bretz's theory come from?
Bretz was unable to say where all the water had come from, but a colleague named Joseph Thomas Pardee was certain that the answer lay in the region around Missoula, Montana, where the surrounding mountains held evidence that an enormous lake had once filled the basin (see Ice Age Lake).
What was the geologist J Harlen Bretz's theory on the creation of the Channeled Scablands?
J Harlen Bretz was a geologist who launched one of the great controversies of modern science by arguing, in the 1920s, that the deep canyons and pockmarked buttes of the arid “scablands” of Eastern Washington had been created by a sudden, catastrophic flood — not, as most of his peers believed, by eons of gradual …
What is Scabland?
Definition of scabland : a region characterized by elevated tracts of rocky land with little or no soil cover and traversed or isolated by postglacial dry stream channels —usually used in plural.
Why is Eastern Washington so barren?
A significant difference between Eastern Washington and the western half of the state is its climate. While the west half of the state is located in a rainy oceanic climate, the eastern half receives little rainfall due to the rainshadow created by the Cascade Mountains.
Who discovered Lake Missoula?

How long did it take for the Scablands to form?
Although Bretz’ concept sparked a lively controversy, most geologists today agree that the Scablands were carved by a flood of unprecedented proportions that took place 18,000 to 20,000 years ago during the Great Ice Age.
Why does McCarthy combine words in the road?
Why is McCarthy combining words in this way? … I think that McCarthy wanted to personify a post apocalyptic alien-like world where humanity is dead and the landscape feels barren.
What is a Bloodcults?
This gang is referred to as the “Bloodcults.” This gang is filled with Marauders and cannibals. When the man and the boy come across this gang they immediately hide and attempt to avoid this dangerous gang.
What was Harlen Bretz 1923 theory?
In 1923, the Journal of Geology published Bretz’s paper, “The Channeled Scablands of the Columbia Plateau,” in which he presented his theory that the unique landscape was created by a massive flood originally called the Spokane Flood.
Article first time published on
How did the flood that formed the Scablands happen?
The scabland was created where the Ice Age floods accelerated across the tilted surface of the Palouse slope, causing massive erosion. Much of the eroded sediment was carried all the way to the Pacific Ocean.
Where did J Harlen Bretz live?
Bretz met his wife Fanny Chalis at college – she was also studying biology – and they married in 1906. They had two children: Rudolf and Rhoda. J Harlen Bretz died, age 98, on February 3, 1981, at home in Homewood, Illinois. He was survived by his son and daughter.
Why are there deserts in Washington and Oregon?
This mountain range meanders from British Columbia through Washington and Oregon to Northern California. It creates the “rain shadow” effect that traps moisture on the Seattle side of the slopes, while leaving Eastern Washington with large areas of semiarid steppe and a few truly arid deserts.
Does WA have a desert?
Deserts[edit] East of the Cascade Mountains, the state’s terrain begins to turn into desert and temperatures often exceed 100 degrees Fahrenheit in regions such as the Yakima Valley , Eastern Washington Desert and the Columbia River Plateau.
Why is Washington state so dry?
As the air descends, it warms adiabatically. This warming process makes condensation and precipitation even less likely because warm air is able to hold more moisture than cool air. This process results in a rain shadow desert for the eastern half of Washington.
Where on earth is there evidence for a megaflood other than the Scablands and Iceland What is the evidence?
Some of them were associated with big ice sheets that blocked the rivers that currently flow north from Russia into the Arctic Ocean. Others were associated with mountain areas, such as the Altai Mountains, the Sayan Mountains, and some of the mountains around Lake Baikal.
What carried the erratics into Scablands?
The Scablands are littered with large boulders called glacial erratics that rafted on glaciers and were deposited by the glacial outburst flooding.
What formed Lake Missoula?
Glacial Lake Missoula formed as the Cordilleran Ice Sheet dammed the Clark Fork River just as it entered Idaho. The rising water behind the glacial dam weakened it until water burst through in a catastrophic flood that raced across Idaho, Oregon, and Washington toward the Pacific Ocean.
Why did lake Missoula Flood?
These floods were the result of periodic sudden ruptures of the ice dam on the Clark Fork River that created Glacial Lake Missoula. After each ice dam rupture, the waters of the lake would rush down the Clark Fork and the Columbia River, flooding much of eastern Washington and the Willamette Valley in western Oregon.
What happened to lake Missoula every few thousand years?
It was the largest ice-dammed lake known to have occurred. The periodic rupturing of the ice dam resulted in the Missoula Floods – cataclysmic floods that swept across eastern Washington and down the Columbia River Gorge approximately 40 times during a 2,000 year period.
How much water is emptied from lake Missoula?
It is estimated that the maximum rate of flow was equal to 386 million cubic feet per second. At that rate, the lake probably drained in a few days.
What are the man's two biggest worries in the road?
They struggle against the cold nights and the man worries about keeping their shoes in good shape and finding their next source of food. They eat sparingly and watch out for the bloodcults, roadagents, and marauders. They stop in an old barn, where bodies hang from the rafters.
What does the Coca Cola symbolize in the road?
The can of coke is symbolic of the old world. It is a glimpse of the old world, an old world icon. Gone and never to be seen again, and gone with it everything that used to be. The coke cola stands for the symbol of society.
What does the boy dream about in the road?
In The Road, Cormac McCarthy uses the Man’s philosophy on dreams to follow the state of mind of his own characters. … In the Man’s situation in particular, dreaming about the past is the sign that he does not exist in the present, a dangerous result when he is the caretaker of his own survival, as well as his son’s.
What does the last paragraph in the road mean?
The last sentence insinuates that man had come into this aw inspiring world unwelcomed; leaving it desolate and destroyed. … That even though he refers to a “once” beautiful world as opposed to where they are today, if there is indeed other life, then maybe things will start to get better in the future.

Who is Ely in the road?
An old man the man and boy meet on the road. He says his name is Ely, but later admits that this isn’t his real name, as he doesn’t want people talking about him or knowing where he is. He says he has “lived like an animal,” and is struck by the sight of the boy.
What was Pardee's evidence?
He discovered the trail of evidence left by Glacial Lake Missoula, a lake created by an ice dam 23 miles (37 km) wide and 0.5 miles (0.8 km) high during the most recent ice age. He discovered that when the dam broke, the water flowed towards the scablands, supporting J Harlen Bretz’s theory of the cataclysmic floods.
What is the difference between uniformitarianism and catastrophism?
Both theories acknowledge that the Earth’s landscape was formed and shaped by natural events over geologic time. While catastrophism assumes that these were violent, short-lived, large-scale events, uniformitarianism supports the idea of gradual, long-lived, small-scale events.
What was the theory of Uniformitarianism?
Along with Charles Lyell, James Hutton developed the concept of uniformitarianism. … This is known as uniformitarianism: the idea that Earth has always changed in uniform ways and that the present is the key to the past. The principle of uniformitarianism is essential to understanding Earth’s history.
What is the name given to the mysterious landscape located 200 miles east of Seattle that is the subject of this documentary?
And, over the whole area, huge boulders are scattered as if a giant had dropped them there. Few places on Earth are as mysterious and controversial as the Channeled Scablands that lie just 200 miles east of Seattle.
