Jim Jim Falls


The Jim Jim Falls is a plunge waterfall on the Jim Jim Creek that descends over the Arnhem Land escarpment within the UNESCO World Heritagelisted Kakadu National Park in the Northern Territory of Australia. The Jim Jim Falls area is registered on the Australian National Heritage List.

Etymology

The English name 'Jim Jim Falls' comes from the local Kundjeyhmi word andjimdjim, meaning 'water pandanus'. Andjimdjim lines the creek below Jim Jim Falls.

Location and features

The waterfall descends from an elevation of above sea level via one drop that ranges in height between into a plunge pool within the creek. The falls are located near the eastern boundary of the national park and south of. In the dry season, access from the Kakadu Highway is possible via a gravel road, with the final 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 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 above the plains, extends over 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.
