The bluffs stretch northwest to southeast over 100 kilometres (62 mi) from the 1,420-metre (4,660 ft) Western Bluff near the town of
Mole Creek to the 1,210-metre (3,970 ft) Millers Bluff, approximately 25 kilometres (16 mi) west of Campbell Town.[5] During the late 19th century the Tiers were known as the Great Western Range.[6]
Features
The Central Highlands, or Tasmanian central plateau, was uplifted from the lower Meander Valley, most probably in the Eocene epoch though possibly earlier, forming the Tiers' escarpment.[7] The plateau's north-east boundary, which ranges from 760 metres (2,490 ft)–1,500 metres (4,900 ft), originated in extensive Tertiary faulting.[8]
This escarpment divides the high, rocky, sparsely inhabited central plateau from the fertile lower land of the
scree slopes.[10]
The face of the tiers has been eroded and retreated approximately 4 miles (6.4 km) since their formation, leaving the mountain Quamby Bluff as a solitary outlier. The central plateau's landform has been changed by glaciation. Valleys under the tiers are filled with talus, mostly bounders with a 25% mix of soil formed from boulder weathering.[11]
