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.
