Harlen Bretz, who studied the geology of the area for years in the 1920s, was the first to propose that the channeled scablands
had been formed suddenly, by a catastrophic flood.
For those of you interested in geology and Mars, I strongly recommend a trip to the Scablands
and the Atacama Desert.
Flood geologists often cite scouring of the Channeled Scablands
in eastern Washington by the Lake Missoula flood and Glen Canyon Dam spillways during the 1983 flood as examples of how this would occur (see Austin, Grand Canyon: Monument to Catastrophe, 46-7, 104-7).
Harlen Bretz, and shows how his methodical fieldwork slowly revealed that the Scablands
were created by water--lots of water--sweeping over the area in a series of massive prehistoric floods.

Cuando en la decada de 1920 Bretz (1969) interpreto, por cierto correctamente, las megaestructuras sedimentarias de las Channeled Scablands
en los Estados Unidos, fue refutado y descalificado porque el tamano de la inundacion que deducia de sus evidencias era descomunal con respecto a las observadas hasta ese entonces.
There is an area in southeastern Washington state in the United States called the Channeled Scablands
As a result, walls of water more than 500 feet high repeatedly swept across Eastern Washington, ravaging the Columbia basin to bare bedrock and creating the scablands
that exist today.
There is evidence of such phenomena in the scablands
of Idaho, Montana, and Washington where, at the end of the last ice age some 11,000 yr ago, a massive ice dam broke at ancient Lake Missoula, sending a cascade of water an order of magnitude greater than the collective flow of all the world's rivers.
Four example are: (1) Aristotelian views on comets (up to the seventeenth century), (2) the idea that meteorites were caused by lightning (most of the eighteenth century), (3) uniformitarian geology and interpreting the Channeled Scablands
, (early twentieth century) and (4) paleontologists and others arguing against the idea that extinctions could be caused by extraterrestrial impacts (late twentieth century).
In the high desert of eastern Washington known as the Channel Scablands
, rough boulders punctuate the rugged basalt landscape.

Lower areas, including the angular scablands
near Horsethief Butte, were stripped of soil by giant Ice Age floods that roared down the Columbia River from a glacial dam in northern Idaho about 10,000 years ago.
