The Channeled Scablands in Washington were formed about 19,000 years ago when glacial Lake Missoula in Montana burst through its ice dam, and a 320 m deep lake emptied in a catastrophic flood that reached the Pacific Ocean. The basaltic terrain of Washington was deeply carved into channels, mesas, and giant dunes as the water scoured the landscape. The image was acquired August 4, 2021, covers an area of 40.2 by 48.8 km, and is located at 47.5 degrees north, 119.2 degrees west.
