Sites of speleological interest

Locations in the table below are usually at a point closest to the site where a GPS fix was possible; this point is sometimes tens of metres from the site. Locations are sorted West→East.

Positions are in °,′,″ and UTM eastings and northings, using the European 1950 datum, as used on most Spanish maps (including the 1:25,000 ‘blue series’). To get WGS-84 coordinates, subtract 4.1″ from N and add 4.8″ to W (an adjustment of ~160m). For more details on this and the grid systems used on the Spanish maps of the area, see Coordinate systems.

Altitudes shown with ‘?’ are suspect – uncalibrated altimeter or GPS.
