Lava Tubes and the Disappearing River

The Rogue River flows, strong and clear, past the Gorge and into the Natural Bridge area.

There is a lava tube there, into which the Rogue River drops.  The river all but disappears under the ground, flowing through several lava tubes. 

It finally emerges with great force many yards downstream.

Not all the tubes flow clearly.  This one is blocked and the water enters, circulates and exits at the same portal.
