ILSE
Ilse
The Ilse is a river that rises at about 900 m above sea level on the northern slopes of the Brocken. During its first few kilometres it flows as a narrow brook, almost invisible to the observer, down the side of the Brocken. Known here as the Verdeckte Ilse it gurgles its way under blocks of granite that hide the stream bed from above.The above text is a snippet from Wikipedia: Ilse (Oker)
