Multnomah Falls, Oregon Poster
Multnomah Falls is the most visited natural recreation site in the Pacific Northwest, with more than 2 million stopping by each year to take in the views. Fed by underground springs from Larch Mountain, the flow over the falls varies but is usually highest during winter and spring. This is also one of the best places in the Columbia River Gorge National Scenic Area to study geology exposed due to historically significant floods.
