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.

One of the most significant sites in the Sydney bason, Devil's Rock has over 67 figures, including Baiame and Daramulan who are are both ends of the rock platform.
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.
