MATIENZO CAVES PROJECT
Caving through the years in and around Matienzo

The linked articles, annual reports and logbooks below document 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, published on Issuu, seem much better viewed on any browser except Internet Explorer.
• 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 in Issuu.
