a goofy pano I put together: The Colliding Rivers is the name of the confluence of Little River into the North Umpqua River at Glide, Oregon, approximately 12 miles east-northeast of Roseburg. It is known as Colliding Rivers because of the nearly head-on angle at which the streams meet, the only place in the state of Oregon where a river meets its tributary in such a straight angle. Prior to the point of the Colliding Rivers, the Little River approaches from the south and the North Umpqua has completed a sharp bend and intersects the Little River.
