Lower Mesa Falls

At Upper Mesa Falls, a thunderous curtain of water – as tall as a 10-story building – pours over remnants of an ancient volcanic super-eruption that spewed ash over much of the current US. A mile south, Lower Mesa Falls repeats the performance; the river continually chiseling away at the solidified ash and lava. Some layers are more than a million years old. Today, Upper and Lower Mesa Falls are the last prominent waterfalls on the Snake River to resist human control.

This remarkable place has nurtured life over the eons. With your help, it will continue to do so for generations to come.



“I gave my heart to the mountains the minute I stood beside this river with its spray in my face and watched it thunder into foam, smooth to green glass over sunken rocks, shatter to foam again. I was fascinated by how it sped by and yet was always there; its roar shook both the earth and me.” Wallace Stegner in Sound of Mountain Water (1980)
