This Place Formed By Megafloods Had Fooled Scientists For Decades.

The Channeled Scablands are a relatively barren and soil-free landscape to the east of the U.S. State of Washington. They extend from the area around Spokane, west to the Columbia River near Vantage, and southwest to the Snake River near Pasco. The name ‘Channeled Scablands’ is derived from the long channels crisscrossing throughout the region, and cutting into the bedrock, called coulees. There are about 150 distinct coulees that have been identified; some of them hundreds of feet deep. The two largest are the 40 miles long Moses Coulee, and Grand Coulee, which is 60 miles. The cataclysmic Missoula floods that were unleashed when a large glacial lake drained, swept periodically across eastern Washington and down the Columbia River Plateau during the Pleistocene epoch, with the last ones occurring about 15,000–13,000 years ago, creating what is today, one of the most fascinating geological landscapes in the region, where only barren bedrock and strange rocky land formations is seen. Most of eastern Washington State is either farmland or mountains, but these large swaths of non-arable farmlands remained a complete mystery to the early settlers.
