Multnomah Falls is a waterfall on the Oregon side of the Columbia River Gorge, found east of Troutdale, amongst Corbett and Dodson, along with the Historic Columbia River Highway. The falls drops in two noteworthy advances, split into an upper falls of 542 feet (165 m) and a lower falls of 69 feet (21 m), with a steady 9 foot (3 m) drop in rise between the two, so the aggregate tallness of the waterfall is routinely given as 620 feet (189 m). The two drops are because of a zone of all the more effortlessly disintegrated basalt at the base of the upper falls.
