-<p>First, look at the <a href="../../indxal.htm">index list of cave numbers</a>. Under the <b>1623</b> heading you will see a lot of caves numbered with 2 or 3 digits, e.g. <a href="/1623/115.htm"><b>115</b> Schnellzughöhle</a> and many more labelled with a year number and some letters and numbers, e.g. <a href="/1623/2015-DL-02/2015-DL-02.html"><b>2015-DL-02</b> Chossy Death Slope Höhle</a>. The former are the Austrian kataster official numbers, the latter are CUCC Expo numbers which are either for caves too insignificant to be issued an official number, or where we have not yet got around to doing the paperwork.

 with a properly-managed and accessible GPS system. However the ~5m practical accuracy of the GPS, the multitude of holes within 5m and
