Eagle Cave is located in the Tietar valley in central Spain, a region with Mediterranean climate and a minor continental influence due to its low elevation. Atlantic fronts are frequently blocked at Gredos Range which is 15km to the north, causing the Tietar valley to be exceptionally wet. The geographic context caused that even during glacial times the water supply to the cave was continuous and no hiatuses are found due to the harsh climate. The cave is less than 20 m deep, presents a stable temperature around 15 ºC and no air currents are appreciable. Three stalagmites have been analyzed for oxygen isotopes and mineral composition, whereas the chronology of the record was based on U-Th dates. The composite oxygen record covers the period from 33 to 9 ka BP with stalagmites formed of both aragonite and calcite, and oxygen isotope values with a range of 3 per mil. Oxygen isotopes in the record depend on many factors and cannot be interpreted as dominated by a sole factor. Corrections have been applied to account for the differences in mineral fractionation factors and for the ice volume effect. The corrected composite record shows two outstanding anomalies with higher isotope values at 24 and 30 ka BP, coinciding with the Heinrich events H2 and H3. A sharp depletion of oxygen isotopes occur at 19 ka BP corresponding with the onset of the deglaciation. The amount of rainfall seems to dominate the oxygen isotope signal in relation to temperature during glacial ages. However, the large modifications of the hydrological cycle during the deglaciation add another major factor controlling oxygen isotopes preventing the record interpretation based on a dominant factor after 19 ka BP. The period before H2 and after H3 has a depleted isotope composition suggesting that this was significantly wetter than other periods during the glaciation. This explains the early dates for local glacial maximum that have been found in the Spanish Central System.
