The video describes Devil's Causeway as a roughly 500-ft-deep gap through a high interfluve into the Snake River; it is now dry and described as a wind gap. The video argues that peak flooding overwhelmed the original Palouse River valley, with spillover across the divide when water rose about 350 ft above the Snake River. It also interprets the parallel strandlines as evidence of receding floodwater and says the Palouse River was later captured into Palouse Canyon after downcutting made that route the path of least resistance. 🏞️
