Multnomah Falls is a waterfall on the Oregon side of the Columbia River
Gorge, located east of Troutdale, between Corbett and Dodson, along the
Historic Columbia River Highway. The falls drops in two major steps,
split into an upper falls of 542 feet (165 m) and a lower falls of 69
feet (21 m), with a gradual 9 foot (3 m) drop in elevation between the
two, so the total height of the waterfall is conventionally given as 620
feet (189 m). Multnomah Falls is the tallest waterfall in the State of
Oregon.
