Wallaman Falls
Wallaman Falls

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.
