A contribution to the description of high mountain climate in the Iberian Peninsula since the Holocene Climatic Optimum is presented in this interdisciplinary study (isotopic, petrographic, and microstratigraphic mainly) of four speleothems from Cueva del Cobre, a cave located in the Cantabrian Mountains (Northern Spain). The speleothems were collected more than a kilometer away from the entrance and ~100 m below the local land surface, which corresponds to a till-covered Pleistocene glacial valley at ~1800 m above the sea level. The climatic interpretation is based on 13 U-Th dates (TIMS and ICPMS), 302 stable isotopes analyses (oxygen and carbon) and the petrographic study of 92 thin sections. The δ18O record allows to compare the present real temperature inside the cave with the ancient estimated temperature while the integration of the different proxies allows to obtain a general description of the environtmental conditions inside the cave and of the exterior climate as well.
