  MATIENZO CAVES
Area maps, photos, documents and site positions

Finances
Details of the accounts kept for the Matienzo Caves Project.  
Caving permit
A permit is issued by the Cantabrian Government and the FCE. The permit is re-applied for every year. Caving outside the area (both new exploration and "tourist" trips) may result in a permit refusal, as happened in 1989 / 1990.
The permit area for 2014 has changed. Llueva, Secadura and Riotuerto areas are "out" and extensions to the north and northwest are "in". New maps and GPS datum are required. The new permit area (blue) and the old (red) are also shown on the Google Map and Google Earth, below.
(The previous permit area is shown on this low detail area map, issued 2006.)
 
Google Map
The Google Map, programmed by Paul "Footleg" Fretwell, displays site entrances superimposed on satellite photos. Descriptions for each site can be shown by clicking on the entrance marker. The computer must be connected to the Internet. Google Maps works best in Chrome or FireFox rather than Internet Explorer.
(Last update: March 2014)
Google Earth
The Google Earth section, collated by Juan Corrin, provides a file to download and use in Google Earth. This shows small-scale geology (including the geological map published with the Matienzo 50 book), all the entrances, cave survey lines, cave surveys, rose diagrams of passage directions, and also selections of sites, ie all the digs, archaeological sites, unexplored sites, sites of biological interest, continuing caves, draughting sites, dive sites, sinks and resurgences. Descriptions for each site can be shown by clicking on the entrance marker. Hi-res surface photos can also be downloaded and used over the standard Google Earth landscape. The computer must be connected to the Internet and Google Earth installed.
(Hi-res jpgs available from 10/2/09) (Last update to Matienzo file: 17/3/2014)
Simple
Simple map showing caves as lines. PDF file.
(Last update: 04/10/2012)
Detailed map
Detailed area map with roads, surface features, permit area and contours. All caves surveyed and with Survex data are shown as pink lines. All site entrances are shown: dots for GPSed entrances and circles for sites that have not been GPSed. The 2014 permit boundary is a red line. Download 36Mb pdf file.
(Last update using ETRS89 : 08/5/2014)
Internet maps
1: SIGPAC An Internet site allowing access to maps and satellite photos of Spain.
2: A Cantabrian government site with detailed maps and a range of orthophotos. (Maps, photos and shape files have been downloaded as the basis for the Matienzo Caves map with cave entrances and centre lines.)
Geological Maps
On-line geological maps. These are dated 1974 or 1976 and produced by IGME (Instituto Geológico y Minero de España). The Villacarriedo map shows the Matienzo depression at the top right of the sheet. Surrounding sheets, eg for Riaño, Entrambasaguas can be accessed from that sheet. (Geological information is also available in the Google Earth file, detailed above.)
Cave survey lines
All the cave sites with Survex data in the Matienzo area shown on a single Aven 3d file. The file has been produced using Survex 1.2.6 which is best to have on your computer to view the file.
Download v1.2.6 Survex / Aven from here. Loch, the viewer component of the Therion cave survey package can also display 3d files. Loch produces red/cyan stereo pairs of the centre line and passage walls and makes an interesting alternative to Aven. Therion can be downloaded from here.
Download Matienzo 1.8Mb 3d file. (Last update: 26/5/2014. Amended magnetic declination December 2013 to align with Eur79 grid. Datum for all sites changed to ETRS89, March 2014)
Also available is a 3d file of the cave survey lines with a full area surface overlay (resolution of 100m). This is definitely better viewed in stereo mode with Loch. (Last update: 26/11/2013)
OruxMaps Files for use around Matienzo with OruxMaps on a Google Android device, eg a smart phone or tablet with GPS, can be downloaded here. These files are maps, satellite photos and cave entrances which move around on screen as the user walks the hillsides. (Latest update: 12/6/2014.)  
PathAway
Files for use around Matienzo with PathAway on a Windows Mobile device with GPS can be downloaded here. These files are maps with marked entrances and cave lines; satellite photos; pemission area. These move around on screen as the user walks the hillsides. (Last update: 15/1/2011)  
Documents

1: Reports and Presentations. Annual exploration feedback reports to the Spanish permit authorities and presentations and reports for external meetings and conferences, eg Hidden Earth.
2: A 6 volume download of all the site descriptions. Last update: 10/06/2014; new ETRS89 grid references)
3: A template for writing up trip reports. If access to the expedition logbook is awkward, please print and fill out this sheet for later sticking in the logbook.
4: For new expedition members, an introduction to the Matienzo Caves Expeditions and expectations. A laminated business card summarising these expectations is available in Matienzo.
5: Surveying. A growing library of help documents for Matienzo cave surveyors.
6: Cave entrances - using GPS in the Matienzo Caves permit area from 2014.
7: Entrance coordinates accuracy, as reported on site descriptions.
8: Planning meetings minutes. Available on the Matienzo Caves Project & Minutes page.
