 Temperatures are regularly monitored by a private weather station installed by Jörg Kachelmann.The noise of the water disappearing underground has led to local folklore and the naming of the outflowpoint "Teufelsmühle" ("Devil's Mill" or "Devil's Grinder").The exact route the water takes underground has not yet been established, and an extensive cave has not been ruled out, but the outflow point is not accessible to humans for investigation.
