Multnomah Falls is a 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. It is credited by a sign at the site of the falls, and by the United States Forest Service, as the second tallest year-round waterfall in the United States.[1] However, there is some skepticism surrounding this distinction, as Multnomah Falls is listed as the 137th tallest waterfall in the United States by the World Waterfall Database (this site does not distinguish between seasonal and year-round waterfalls).[2][3]

Underground springs from Larch Mountain are the year-round source of water for the waterfall, augmented by spring runoff from the mountain's snowpack and rainwater during the other seasons.

A foot trail leads to Benson Footbridge, a 45-foot (14 m)-long Starvation Creek. The footbridge is named for Simon Benson, who financed the bridge's construction in 1914 by Italian stonemasons.[4]

Benson soon gave Portland land that included most of the falls as well as nearby Wahkeena 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.[5] The lodge is now on the National Register of Historic Places.[5]

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.

On Labor Day in September 1995, a 400-ton boulder, loosened by erosion, fell 225 feet (69 m) from the face of the waterfall into the upper cascade pool, above Benson Bridge. It caused a 70-foot (21 m) splash of water and gravel to wash over the footbridge, causing minor injuries to twenty members of a wedding party that happened to be on the bridge posing for photos at the time.[6]

On January 9, 2014, a falling rock damaged a portion of the bridge walkway and concrete railing, leading the Forest Service to close the bridge until repairs were made. The bridge is now repaired.[7]
