Mount Barrington, a mountain that is part of the Mount Royal Range, is located on the Barrington Tops plateau in the Mid-Coast Council within New South Wales, Australia and has an elevation of above sea level. 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 basalt flow, which covered much of the Barrington Tops plateau. The lava was up to thick. The extensive rainforests in the area grow on much of the resultant red/brown soils. Gemstones such as zircon, sapphire, sapphirine and ruby were formed from the volcano. 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.
