Geology

The range is composed of a diverse group of mostly igneous rock
Igneous rock
Igneous rock is one of the three main rock types, the others being sedimentary and metamorphic rock. Igneous rock is formed through the cooling and solidification of magma or lava...

History

Historically, the region was home to the Raki-warra clan of the local Darumbal indigenous people. It received its English name from the Archer brothers
The Archer brothers
The Archer brothers were among the earliest settlers in Queensland. They were explorers and pastoralists. Seven sons of William Archer, a Scottish timber merchant, they spent varying amounts of time in the colony of New South Wales, mainly in parts of what later became Queensland. A substantial...

in 1853. A small amount of gold mining took place in the 19th century, and grazing leases were issued in 1900. The area was declared a timber reserve in 1940 and logged, with ironbark, white mahogany and lemon-scented gum being the main trees harvested. Grazing ended in 1974 with the conclusion of the last lease, and logging ceased in 1985.
