Aboriginal people lived in the area surrounding today’s Sydney for over 20,000 years. The clans who resided in the Blue Mountains were the Darug and Gundungurra. There are several examples of their engravings. Some are about 5,000 years old. This “simple figurative” carving of a kangaroo is at the Kangaroo Street Aboriginal Site in Lawson. It was probably chiseled into the sandstone using a pointed shell or rock. Archaeologists believe this may have been an “increase site” created during a ceremony to wish for more food such as kangaroo meat
