Geology
Late Devonian fluvial sediments (conglomerate, sandstone, mudstone) often referred to as the ‘red beds’.
Landform
Steep hills to steep mountains at elevations ranging from 150 to 500 m. The Turton map unit occupies the higher valley slopes around Combienbar and Buldah, generally on slopes more than 32%. The adjacent land on more gentle slopes land is mapped into the Combienbar map unit.
Native vegetation
Shrubby dry forest.
Soils
The depth to rock is variable as is the amount of rock outcrop. Any soil that does develop is usually red to brown in colour and has a high fine sand and silt content.
Land use
Almost all the map unit is uncleared and most is public land.
