Location and features
The waterfall descends from an elevation of 259 metres (850 ft) above sea level via one drop that ranges in height between 140 and 200 metres (460 and 660 ft) into a plunge pool within the creek. The falls are located near the eastern boundary of the national park and 28 kilometres (17 mi) south of . In the dry season, access from the Kakadu Highway is possible via a 60-kilometre (37 mi) gravel road, with the final 11 kilometres (6.8 mi) suitable for four-wheel drive vehicles only. However, during much of this period the falls dry up and do not flow. In the wet season when the falls are at their most spectacular, it is impossible to drive any vehicle into the area and are best viewed from the air together with the nearby Twin Falls.
It is believed[by whom?] that 140 million years ago much of Kakadu was under a shallow sea. The prominent escarpment wall formed sea cliffs and the Arnhem Land plateau formed a flat land above the sea. Today the escarpment, which rises to 330 metres (1,080 ft) above the plains, extends over 500 kilometres (310 mi) along the eastern side of the national park and into Arnhem Land. It varies from vertical cliffs in the Jim Jim Falls area to stepped cliffs and isolated outliers in the north.
