 The discovery of the "Wolkenschloss" (Castle of Clouds), another large, air-filled cavern, and the so-called "Landweg" (land-way), a long, open cave river behind the Mörikedom, were great successes for the "Arbeitsgemeinschaft".Hasenmayer continued his attempts to explore the cave system in his cave submarine, "Speleonaut".Since 2002 the "Arbeitsgemeinschaft Höhle und Karst Grabenstetten" (Cave and Karst Consortium of Grabenstetten), as a part of their work on a neighboring cave system, the "Vetterhöhle", have attempted to dig a dry entrance into the Blauhöhle.
