The photo above shows breathtaking Multnomah Falls at the Columbia River Gorge -- on the Oregon side of the Columbia River. It's fed by underground springs and snowmelt runoff. Multnomah Falls is listed as the second highest year-round waterfall in the U.S., dropping a total of 611 ft (186 m) in two separate falls -- the upper falls is the most impressive, plunging 542 ft or 165 m. The rock face cuts through six different lava flows. Lewis and Clark passed by the falls in 1805 on their trip of exploration along the Missouri and Columbia Rivers. Photo taken on August 2, 2011.
