This waterfall is very tall – the tallest cascade falls uninterrupted for 165 m but several more factors make this waterfall special: such as the scenic pedestrian bridge between two drops of the falls and the easy accessibility from the highway.
Columbia River Gorge
The Cascade Range is crossed only by three larger rivers and the largest is the mighty Columbia River. As the mountains gradually rised over the last 17 – 12 million years, the river cut a spectacular gorge through the mountains. This gorge is some 130 km long and up to 1,200 m deep.
Thanks to high amount of precipitation here have formed numerous smaller and larger streams, which are running towards Columbia River. When these streams reach the gorge, often spectacular waterfalls are formed. There are more than 90 perennial waterfalls known on the southern, Oregon side of the gorge.
In 1913 – 1922 along the Oregon side was built scenic highway – the first such planned tourist route in United States. Some decades later next to it was built Interstate 84.
The waterfall
Waterfall has been known to local people since prehistoric times. People of European descent most likely learned about these falls around 1805, when the Lewis and Clark Expedition reached this area. Name “Multnomah” originates from the Chinook word which denotes the lower reaches of a river, here – Columbia River. First this word was used to name the Multnomah County and then, around 1860 – also to name the most prominent local waterfall.
Multnomah Falls are falling over basalt rock which was exposed by one of the gargantuan lake outbursts (Mussoula Floods) which took place here during the Ice Age. Waterfalls are fed by spring in the nearby Larch Mountain. This spring is an abundant source of water throughout the year. Often the stream is supplemented by rainwater and melting snow.
Waterfall has three main drops. The upper one (some 3 m tall) is nicknamed – Little Multnomah and often has not been included in the full height of the falls. Soon after this drop comes the tallest (165 m) drop. As it hits the ground, follows short run and then the Multnomah Creek makes the final, nearly vertical 21 m tall drop which ends in a plunge pool.
In 1914 between the two tallest drops of the waterfall was built 14 metres long footbridge. It was financed by lumber businessman Simon Benson and is called Benson Footbridge. This gracious structure has become an integral part of the breathtaking view on the waterfall, the bridge accentuates the giant size of falls.
Benson and other influential local people rightly considered that the beautiful landscape of Columbia River Gorge has a good tourism potential. It seems that Multnomah Falls in a way were a key point in their activities – here started the planning of the first scenic road in the United States, here was built also modern (for its time) hotel – Multnomah Falls Lodge. Around the falls was developed a network of footpaths.
Nowadays Multnomah Falls and their surroundings are justly popular hiking area and one of the symbols of the natural beauty of Pacific North-West.
