Maroota is located to the north-west of Sydney, just south of the Dharug and Yengo National Parks. It has a high concentration of (known) Aboriginal sites, with 12 engraving sites being located in one square kilometre at Maroota south of the Hawkesbury River; significantly higher than the Mangrove Creek valley which was also systematically sampled. The original inhabitants of the Maroota area were the Darug people.
Perched above Old Northern Road on a solitary mass of sandstone, a faded engraving Baiame watches the traffic go past. The engravings of this god and eleven other figures have survived attempts to straightenor widen the road.
