The cave of Santa Catalina with Upper Magdalenian, Late Magdalenian and Azilian occupations is one of the key sites for the study of the last Paleolithic hunter-gatherers of the Cantabrian Region. A detailed monograph edited by Eduardo Berganza and José Luis Arribas (2014) has been recently published with all the studies relative to site’s stratigraphy, chronology and biological remains (plants, fauna, human). Also, a paper by Roselló et al. (2015) dealing with fish remains has been just published in JAS Reports. These results were also presented by E. Berganza at the Arkeologi Museoa in 2012 (video). The material culture (lithic and bone industry, portable art) will be published in a second volume.

In 2000 I participated in the excavation of Santa Catalina under the direction of Eduardo Berganza. It was my third prehistoric excavation and it was totally different from anything else. The site is located in a breathtaking landscape, hanging over the sea in a limestone cliff, close tho the Santa Catalina lighthouse and convent, in the beautiful coastal town of Lekeitio. Accessing the cave was an adventure itself, but the risk was worth it.

The site was incredibly rich, there was almost no sediment and grace to the careful digging and sieving we were able to recover every tiny remain left there by the occupants between 15-10.5 kyrs. Small lithic tools, bone tools, decorated tools, ornaments, bone fragments, shells, even fish-bones appeared unnumbered in front of our eyes.

This 1999 field season was the last one of an investigation initiated in 1982. The site was initially discovered by J. M. Barandiarán, the father of Basque Archeology, in a short visit made in 1964 during the excavation of Lumentxa, an important site located few kilometers away. The excavation project started in 1982 intended to understand late Upper Paleolithic occupations in the Eastern Cantabrian Region. This objective was fulfilled and Santa Catalina can be considered one of the key sites for late Pleistocene.

The site, excavated in 9m2, revealed a neat stratigraphy composed by four levels. Level IV was sterile, level III presented some fireplaces and was attributed to the Upper Magdalenian; level II has many and successive fireplaces made during the Late Magdalenian; and finally level I corresponded to the last Paleolithic hunter-gatherers of the Azilian. A total of 23 radiocarbon dates bracket the human occupations at the site. Level III was formed between ca. 15-13.8 kyr cal BP, level II between 14-12.5 kyr cal BP and level I between 12.5-11 kyr cal BP.

The detailed analysis of the variation of different biological remains is representative of the climatic changes that occurred at the end of Pleistocene. A trend of continuous climatic amelioration can be observed from level III to level I. The plant record is not so well preserved, specially polen remains, but the presence of juniper, pine, birch, ilex and arbutus has been documented through anthracologic analyses. The faunal record, on the other hand, is very rich. Bones and shells at the site count for thousands, with an incredible variability of species of micro-vertebrates, mollusks, crustaceans, echinoderms, fishes, birds and macro-mammals. These bones and shells were accumulated by different agents, mainly humans and birds, being informative not only for environmental reconstructions but for understanding the subsistence strategies practiced by the inhabitants of the cave.

The paper by Roselló et al. deals specifically with the fish remains. With more than 4500 fish remains corresponding to 32 species (plus 11 genera) the Santa Catalina record is the richest paleolithic site in fish remains of the entire Atlantic facade, and thus is one of the best sites for describing the origins of systematic sea-fishing in the region. Previously sea-fishing was documented at sites like Cueto de la Mina or Aitzbitarte III, in this case associated to Evolved Aurignacian-Early Gravettian occupations (ca. 33-29 kyr cal BP), but on a clearly inferior scale. At Santa Catalina fishing was a complex activity involving the capture of very different species found close to the site. It probably also played an important role in subsistence strategies. The uniqueness of Santa Catalina can be explained by the quality of the excavation and the proximity to the sea-shore. Probably this record is partially biased by the role of birds as accumulator agents. Although taphonomic analysis is still in progress, the assemblage size and diversity suggest that most of the remains were introduced there by humans.

Beside fishes, Santa Catalina is also very rich in other marine resources as clams, limpets, crustaceans and echinoderms. Throughout the sequence some variation in the exploitation of these resources have been identified, being more relevant at levels II (Late Magdalenian) and I (Azilian).

Santa Catalina has also an spectacular birds assemblage. The analyses made by M. Elorza and V. Laroulandie, show that a huge diversity of species were hunted and used by humans, to obtain meat, bone tubes, claws and feathers. The most intensively exploited birds are the anseriformes, specially the mallard, being the most represented species in levels II and I. The level III shows a more complex record also with anseriformes but with other species as the snowy owl, the great auk or gulls. The great variability of species is interpreted by M. Elorza as the result of fortuitous captures of sea-birds that got caught in the nets displayed for salmon fishing, but the systematic exploitation of some species suggest that, maybe, they were intentionally hunted.

The macro-mammal assemblage, studied by P. Castaños is also very rich. It has a typical late Pleistocene composition, dominated by red deer. Interestingly, some less frequent species as reindeer, seals and cetaceans are also represented. The presence of reindeer in the Iberian Peninsula has been thoroughly discussed in a recent paper by Gómez-Olivencia et al. (2014). In this discussion the site of Santa Catalina is very relevant because it contains many reindeer remains, even in the most recent (Azilian) levels, being the second most represented species in level III. Also, a reindeer molar recovered from level I has been directly dated in 9760+/-65 uncalBP. It is also noteworthy the presence of Crocuta crocuta (spotted hyena) teeth at level III. Until direct dating is available, and if we consider that the stratigraphic position is correct, this would be one of the latest occurrences of hyenas in Europe (see Stuart and Lister 2014, and Diedrich 2014 for more details).

Summing up, Santa Catalina site has an incredible rich faunal assemblage which describes in detail the late Upper Pleistocene environment around the cave. It reveals also the complex nature of the subsistence strategies practiced during Upper-Late Magdalenian and Azilian. Many different species, from very different environments were captured and consumed there. The hunting techniques and strategies must have been also very complex and innovative, at least for capturing sea-fishes and birds, and probably the animal processing techniques were also complex, including the use of meat, bone, hide, feathers, etc. This describes a broad spectrum subsistence strategy that was not strictly driven by the need of nourishment. It was indeed highly influenced by the need of raw materials and probably by other culturally mediated needs.

In 1930 the French spelunker N. Casteret discovered several parietal engravings of Palaeolithic age in Alkerdi cave. Later on in 1974 a detailed study of these engravings was made by I. Barandiarán, who also, more recently, has excavated the cave. In 2014 more than twenty new figures were discovered by D. Garate and O. Rivero in an almost unknown sector of the cave called ‘Galería de los Bisontes’.

One year ago I helped Diego Garate to the cave We went to make photos and document the rock art. Diego told me the nature of the findings, but the reality exceeded any description. The Gallery was narrow, so tight that it was impossible for two persons to stay one beside the other. We entered creeping, pushing ahead all the equipment, then we stopped in front of the left wall.

I was able to see some faint bluish lines, but until Diego started pointing the engraved lines with his finger I was unable to realize that I was in front of a big bison. The figure was impressive, 67 cm long, with the eye, the horns and the snout carefully represented. Three lines drawn in the flank of the animal represented nailed spears or arrows. The animal, with his tongue sticking out, seemed hurt, almost agonizing. I was shocked by the strength of the representation but then Diego started pointing the different figures and I realize the beauty and the relevance of the discovery he made.

The cave of Alkerdi is located in Navarre, just beside the actual frontier between Spain and France. It opens in the slopes of Arleun mountain, where are also located other archaeological caves as Alkerdi 2 or Beroberria, which has a Late Upper Palaeolithic sequence excavated by I. Barandiarán.

Alkerdi is a relatively small cavity which can be divided in different sectors. The entrance chamber has a very low ceiling and here were made the archaeological excavations of a single Gravettian layer. At the end of one narrow passageway which starts from this entrance chamber is located the already known decorated sector. After the main chamber, a second one is present at the back of the cave. Here, also a small passageway opens on the left wall. In this narrow place is where the new figures have been found.

These new figures have been studied with innovative methods of photography, photogrametry and 3d laser scanning. Also advanced methods of image editing and infographics have been used to record and show the engravings.

The figures were made with superimposed faint engravings, probably due to the hardness of the wall, creating complex lines which nowadays are still clearly visible. The figures are small and adapt to the narrow space where they are represented. In fact it is quite surprising that such a narrow space was used, but similar examples have been found at Mas d’Azil or Etxeberri. The most represented animal is bison, followed by horse. There are also some less clear figures as a possible doe and a wolf. Bisons have been represented in great detail following the conventions that are typical during the Middle Magdalenian at the Pyrenean region: S profile horns, beard and hump represented with parallel tracings, representation of eye, ear and snout; occasional representation of tongue, hoofs and hooks, sex, etc. Horses have also typical conventions as the detail of anatomical parts or the representation of the mane with parallel tracings.

The rock art discovered at Alkerdi cave is clearly related with the rock-art sites found at the close Gaztelu hill (Isturitz, Oxocelhaya and Erberua). Also, the ‘pyrenean’ style of the representations is related with classic sites as Niaux, Fontanet or Tuc d’Audoubert. This discovery enhances the knowledge of the rock art at the region and offers new data to assess the mobility of Middle Magdalenian populations, helping to understand the existence of a ‘global’ art expression in Western Europe 14.000 years ago.
