Marker Name: The Hidden River
Marker Text: The Rogue River flows through a lava tube behind the wall of rock across the channel, becoming a “hidden river.”
When the water is low, the entire river goes through the tube, and several potholes may be visible below this viewpoint.
Potholes are nature’s artwork . . . formed when small rocks are trapped in holes in the lava and swirled by flowing water. The resulting action slowly grinds the solid rock away, leaving bowl-shaped potholes.
