Striebel, T. & Eckenfels, J.: Two Caves at the Hoher Ifen
  • Two little caves near Riezlern (western part of Austria, near the border to Germany) are described. One of them is a well-known small natural bridge which was eroded by a stream still active in spring times. The second cave is formed along a bedding plane, also active in spring times and terminates at a siphon (sump) filled with water and muddy loam.
