Marker Name: Salmon River Canyon
Marker Type: Roadside
Marker Text:
Some 15 million years ago, Salmon River ran across great Miocene lava flows above here and started to carve this deep canyon.
Then this part of the earth’s surface gradually rose. As the mountains were rising, the river cut down into the older rock below. Many other northwestern rivers cut similar gorges. The Snake flows through Hell’s Canyon -- deepest of them all -- 8 miles west of here.
