The iconic Palouse Falls that has been deemed the official waterfall of Washington State is not to be missed. At the end of the last ice age, repeated glacial floods, known as the Missoula Floods, swept across eastern Washington carving out the unique scablands landscape we see today. Among the coulees, potholes, buttes, and plateaus, Palouse Falls remains as one of the magnificent and lasting remnants of these glacial floods. It is the only major waterfall left along this thousands of years old glacial flood path.Standing at a height of 198 feet and surrounded by striking basalt cliffs, the powerful waterfall lies on the Palouse River upstream of the confluence with the Snake River.
