The first German speleological expedition to the Himalaya went to the terrace sediments of Pokhara, Nepal. New discoveries could be made in the longest cave of the Himalaya (Patalae Chhango or Harpan-River-Cave) and other caves were surveyed for the first time. Due to the observations the classification of conglomerate-caves as pseudokarst-appearances has to be questioned.
