Cave Systems

   Cave systems are defined here as cave passages usually with more than one entrance which can be traversed by cavers or cave divers, or are proved by water tracing. Some "systems" have only one entrance but the length (>2.5km) warrants inclusion here. Currently, not every system has separately numbered (or GPS'd) entrances, e.g. Fuente Aguanaz (0713).
    The major system names are usually named after the area or geographical features; minor systems are arbitrarily named, perhaps as combined names.
   [Note: There are inconsistencies. For example, Boyones (water-traced) is shown as part on the Four Valleys System whereas El Cubillón is not (yet) shown below as part of the Aguanaz system, even though it has been traced to that resurgence. (Should the length of Cubillón be shown in such a system?)
   Although the policy is to give each "hole in the ground" a separate code, this is not always carried through. For example, the middle, window entrance to Aguanaz is code-less.]
