Now the remnants of a volcano, Mount Barrington, formerly the Barrington Volcano, erupted near its present peak between 44 and 54 million years ago. The eruption caused a 700-cubic-kilometre (170 cu mi) basalt flow, which covered much of the Barrington Tops plateau. The lava was up to 1,000 metres (3,300 ft) thick.

The extensive rainforests in the area grow on much of the resultant red/brown soils.^[2][3] Gemstones such as zircon, sapphire, sapphirine and ruby were formed from the volcano.^[4] Nearby Careys Peak is considered a vent in this extinct shield volcano. The surrounding area is covered by sub alpine Snow Gum woodland, with rainforest on the escarpment edge and in fire free gullies.
