Garigal National Park has extensive Aboriginal history, with over 300 Aboriginal sites recorded. These include cave art, rock engravings, shelters, middens and grinding grooves. Many other sites in the Northern Beaches area are preserved in Crown land, reserves and land managed by the Metropolitan Local Aboriginal Land Council.
Interpreted as a hunting scene, this small Aboriginal engraving site near the Cook Street Trail features a large emu/turtle, superimposed with a man (or hunter). Nearby sre two snakes.
A significant Aboriginal rock engraving site in Allambie Heights, Gumbooya Reserve has 70 figures (many very weathered or no longer visible) in three groups.
