Colliding Rivers

Colliding Rivers is where the Little River and North Umpqua River meet at a direct angle, creating strong currents and waves in a basalt pool formation. The site is accessible from Highway 138 and displays the force generated by this head-on collision of two waterways.

The confluence point was part of the Pacific Ocean millions of years ago, leaving marine fossils and geological evidence in exposed rock layers. This ancient geological history shaped the rock structures that visitors see today.

The area draws local fishermen and geology enthusiasts who examine the exposed shells, shale, silica, and coal deposits visible in the rock.

The observation point is accessible year-round from Highway 138 and offers safer conditions for swimming and rock collecting during summer months. The location is easy to spot and requires only a short walk from the parking area.

This is the only known location in North America where two rivers collide head-on, producing visible water force interactions that are rarely seen elsewhere. The spot draws adventurers and nature enthusiasts eager to witness this rare natural phenomenon.
