The waterfall is fed by perennial springs originating from Larch Mountain, ensuring flow even during dry summer months.
Simon Benson, a lumber tycoon, gifted the land and the iconic stone bridge to the City of Portland in 1915.
The falls are situated within a deep canyon created by massive Missoula Floods that swept through the region approximately 15,000 years ago.
The water descends 542 feet in the upper tier and 69 feet in the lower tier, separated by a 9-foot transition zone.
The Benson Bridge stands 105 feet above the lower observation pool.
Multnomah Falls is the tallest waterfall in Oregon, with a total drop of 620 feet cascading in two major tiers. The site features the Benson Bridge, a stone arch structure constructed in 1914 that provides an elevated viewing platform midway up the falls. Fed by underground springs from Larch Mountain, the water flow remains consistent throughout the year. The surrounding Columbia River Gorge National Scenic Area offers a temperate rainforest ecosystem. Visitors access the falls via a paved path leading to the primary observation deck located at the base. The site is managed by the USDA Forest Service. Geologically, the falls are carved into basalt rock formed by ancient volcanic activity.
