- •
Deglaciation stages in Sierra Nevada (southern Spain) by applying 36Cl cosmogenic exposure dating to 28 samples.
- •
Shortly before the Last Glacial Maximum, the glacier occupied the valleys, with transfluences between them until 19 ka.
- •
The glaciers expanded again during the Oldest Dryas and refilled the valleys by the last time.
- •
During the Younger Dryas small glaciers developed only in cirques shaped on east-facing slopes.
- •
With the onset of the Holocene, rock glaciers developed inside the deglaciated cirques on some valleys.
