On the Eastern side of Gibraltar is located the large aeolian accumulation of Catalan Bay (Catalan Sands Formation). These climbing dunes were generated in several episodes during the Marine Isotope Stages (MIS) 5 to 2, as reflected by OSL dates performed in basal sections and nearby caves and shelters. The source area was an exposed plain that existed to the east of the Rock and extended down to −80 m, with cliffs reaching +6 m. The prevailing winds that generated this accumulation ranged from E to S during this period. The effect of these winds was to transport the dunes from the SE and progressively pile them against the slopes of the Rock, growing the deposit from North to South.
