Landforms
It is the source of the Severn River, which is the starting point of the Darling River. This Severn River is a separate river from the New South Wales eponymous river. The river has cut a 10 km long gorge through hard trap rock. Some of the Severn River's tributaries have carved gorges and contain waterfalls.
The area has a complex geological history. Before it was a national park the land was mined for molybdenite, arsenic, tungsten, copper, gold and tin. The park is also home to the most northerly population of wombats along with nearby Girraween National Park. Tiger quolls and platypus are other species that may also be found.
