The articles, annual reports and logbooks listed below record the caving activities around the Matienzo depression and beyond. The earlier reports have been previously published in Caves & Caving or, since 1998, been specially written for this web site. Logbooks for the 1960's and 1973 are those from la Sección de Espeleología del Seminario Sautuola (SESS), including the expeditions.
Notes:
• Some of the logbooks contain "adult/juvenile humour" and may offend.
• Each logbook is not necessarily a complete record.
• The logbooks, initially published on Issuu, will be removed as that site is now charging, as are most other platforms. (February 2023).
• Each logbook can be downloaded or viewed as a flip book with the Chrome browser (using the Pageflip PDF viewer extension). A similar extension in Microsoft Edge is not as capable.
• Because a front and back cover have been added to each logbook, page numbers in these logbooks do not agree with those in the Logbook Search facility, e.g. a page 5 in the Logbook Search will be a page 7 when the pdf is viewed or downloaded.
• Logbook entries can be searched using the Logbook Search facility
