By 1855, the alluvial gold was running out and reef mining commenced.

Hydraulic sluicing operations commenced in the 1870's and continued through to the 1880s.

Water for the sluicing was delivered to the site by a water race and then directed at the gold-bearing deposits.

The water race was approx 30 miles long and could only operate during the wetter months.

The result of this sluicing is now known as the "Pink Cliffs"

Gold mining operations were finally banned because of environmental damage.

The formation comprises granite of various hues and hardness.

There is now a picnic area, walking track and information boards that cater for the interested visitor.
