[1] It is so named as an ibex skull was found within the cave which would have been hunted by the Neanderthals of Gibraltar thousands of years ago.

The sand from the slopes that was then beneath the water catchments was extracted and transported along a conveyor belt system to the road below for industrial use.

[3] In 1985, when workers began removing sand from above the water catchments, they discovered the entrance to a small cave.

They recovered stone artifacts and bones until ordered to stop by George Palao of the Public Works Department.

Palao gathered the collected items and arranged for the cave to be sealed according to notes found years later in a vault at the Gibraltar Museum.
