These are the highest, permanent clear drop waterfalls in Australia.
Stony Creek tumbles 70 metres off the Seaview Ranges before plunging 268 metres in a clear single fall.
They are about 100km north of Townsville in Queensland.
The
waterfall is formed by a tributary of the Herbert River, Stony Creek,
which plunges over an escarpment in the Seaview Range.
The
geological history of the formation may be traced back some 50 million
years,
when the uplift of the continental margin in this region resulted in
the ancestral Herbert River
to change its course from westwards to eastwards.
As a result it began to cut through the raised igneous substrata en-route
to its outflow in the Coral Sea.
The gorge produced by this erosive action gradually retreated inland
along the Herbert River's course,
and in the process eventually causing tributaries such as Stony Creek
to be suspended, forming the waterfall.
