Los Scablands: esculpidos por el agua

The video explores the Scablands in Washington State, formed by catastrophic floods from Lake Missoula, created by a glacier in Montana. These floods, occurring 15,000 years ago, dramatically reshaped the landscape, carving deep canyons and distributing sediment over vast areas. The repeated filling and emptying of Lake Missoula over centuries further sculpted the terrain, demonstrating the powerful influence of ice and water on Earth's geology.
