Coloured Sand Cliffs of Cooloola National Park: Brittle Pink

The high dunes of Cooloola have been accumulated in past ice age eras and then partially eroded and sculpted into high sand cliffs during the higher sea-levels of inter-glacial periods.

This site is an especially fragile piece of the ecosystem, built on these ancient sands. The sands have been consolidated and eroded to reveal the subtle colours created by iron elements dyeing the quartz and orthoclase grains of sand.

Some of the iron binds the compressed sand such that it is brittle and fractures as shown by the sharp edges and cracks.

This is the beauty and fragility of Cooloola National Park.
