'''Multnomah Falls''' is a Waterfall on the Oregon side of the Columbia_River_Gorge, located east of Troutdale, between Corbett and Dodson, along the Columbia_River_Highway. The falls drops in two major steps, split into an upper falls of 542 feet and a lower falls of 69 feet, with a gradual 9 foot drop in elevation between the two, so the total height of the waterfall is conventionally given as 620 feet. Multnomah Falls is the second tallest year-round waterfall in the United_States.
Underground springs from Larch_Mountain are the year-round source of water for the waterfall, augmented by spring runoff from the mountain's snow pack and rainwater during the other seasons.
A foot trail leads to Benson Footbridge, a 45-foot-long Footbridge that allows visitors to cross 105 feet above the lower Cascade. The trail continues to a platform at the top of the upper falls, the Larch Mountain Lookout, where visitors get a bird's-eye view of the Columbia Gorge and also of "Little Multnomah", a small cascade slightly upstream from the "upper" falls, which is not visible from ground level. The footbridge is named after Simon_Benson, who had the bridge built in 1914.
Benson soon gave Portland land that included most of the falls as well as nearby Wahkeenah_Falls. The Oregon-Washington_Railroad_and_Navigation_Company gave Portland land at the base of Multnomah Falls contingent upon their agreement to build a lodge at the site. A few years later architect A.E._Doyle, who designed the Meier_&_Frank_Building, was commissioned by the city to design the lodge, which was completed in 1925. The lodge is now on the National_Register_of_Historic_Places.
In contrast to other falls along the Gorge, the Multnomah area is also reachable via a stretch of I-84 east of Troutdale,_Oregon. The rest area and tunnel under the road (as well as the Union_Pacific_Railroad tracks) allow Interstate travelers from either direction to stop and visit the falls.
