Key Mountain Ranges in Western Australia
Western Australia contains several distinct mountain systems rather than a single continuous chain. These ranges vary widely in age, structure, and ecological function, and they reflect the long tectonic history of the Australian continent.
- The Hamersley Range in the Pilbara is a plateau-mountain landscape dominated by iron-rich rocks and steep gorges.
- The Kimberley region features table mountains and dissected plateaus underlain of ancient sandstone and basalt.
- The Stirling–Roe Range area in the southwest supports jarrah and marri forests on lateritic soils.
- The Darling Range east of Perth is a prominent escarpment formed by the tilted Darling Fault, creating forested slopes and river valleys.
- Musgrave and Petermann Ranges in central Australia represent older, more eroded forms, sitting within the arid zone.
Together, these areas contribute to WA’s diverse landforms, each with its own elevation range, geology, and land management context.
