SANDSTONE COUNTRY IV / June 2011 Part I

Robin Falls is a small reserve along Dorat Road and about 18 km from the township of Adelaide River. The falls cascade off sandstone escarpment which is bounded by floodplain to the east and the Adelaide River to the west. The area is predominantly private land. The falls are spring fed and water is present throughout the dry season and attracts macropods like the Agile Wallaby, Antilopine Wallaroo at the base and on the cliff-faces, the Short-eared Rock-wallaby, and the Narbalek (elegant rock-weasle).

Motor Car Falls follows an historic vehicle track where, in 1946, the first motorcar entered the region. An impassable creek marked the end of the journey. Ever since, that creek has been called Motorcar.

SANDSTONE COUNTRY IV / June 2011 / Part II

Baroalba Creek is the main drainage for Mount Brockman, a large, irregularly shaped massif sitting on the plains a few kilometres away from the edge of the Arnhem escarpment. Its maximum dimensions are about 11 kilometres east to west and 15 kilometres north to south. Its maximum height is about 300 metres above sea level, about 240 metres above the surrounding plain. While the edges of the massif are extremely rugged and steep, much of the centre consists of a large basin drained by Baroalba Creek. The rugged nature of the approaches prevented buffalo from reaching the basin, making this one of the few undisturbed areas in Kakadu. The area is full of rock shelters that were used by Aboriginal people over the millennia. It contains what may well be the greatest concentration of Aboriginal rock art in Australia, dating from the most ancient to the most recent.
