Andara, Picos de Europa

The Picos de Europa is a range of mountains 20km inland from the northern coast of Spain, forming a westerly extension of the Cantabrian Mountains. The range consists of three main areas, the Western, Central and Eastern Massifs divided by the Cares and Duje rivers.  In the early seventies the Eastern Massif, known locally as Andara, drew the attention of a group of cavers from Lancaster University Speleological Society (LUSS).

In the early years exploration was mounted from the mountain village of Tresviso and exploration was dominated by the resurgence cave Cueva del Nacimiento (Cueva del Agua) located at the foot of the mountain range. This resurgence flows into a canal that contours the Urdon gorge with an average flow of 2 m3/s and the cave leads to over 12 km of surveyed passage and a current height gain of over 534m (2017).  The catchment is some 40 km3 and includes caves such as Sima de Los Senderos (Sima 56) at -1169m deep and Torca Jou Sin Tierre (CS-9) at -1203m deep.

The survey data held here consists  mainly of the survey data from the 2010 and later expeditions.  Oriignal raw data for caves mapped prior to this is harder to come by and / or lost.

Where a published survey exists, but the original data remains to be found or re-entered a very rough digital representation has been added to give an idea of the trend of the cave.

The caves have been split into various areas.  Within each area is a set of entrance coordinates for all caves in the area.  These coordinates are variously taken from the maps in the 1970's and 1980's and, more recently, GPS.  In some cases there has been found to be a 300 m discrepancy between the old map and GPS coordinates- updating the coordinates is an ongoing task.
