Editing Springbrook National Park (section)

===Landforms===
The southern cliffs in Springbrook and [[Lamington National Park]] are part of the remnants of the northern rim of the huge, ancient [[Tweed Volcano]]. The Springbrook National Park comprises four reserves on and around the plateau: Springbrook Plateau section along the crest of the plateau; Mount Cougal section to the east; and Natural Bridge and Numinbah sections to the west. The cliffs are resistant, volcanic based [[rhyolite]].<ref name="naq">{{cite book |title=Natural Areas of Queensland |last=Shilton |first=Peter |year=2005 |publisher=Goldpress |location=Mount Gravatt, Queensland |isbn=0-9758275-0-2 |pages=186–190}}</ref> Rock overhangs are common and massive rock falls sometimes dislodge house-sized rocks.<ref name="naq"/>

The national park preserves rainforest and eucalypt forests in the cliff-lined headwaters of rivers and creeks flowing to the Gold Coast, in particular, the Nerang River on the plateau's west and Little Nerang River to the east, both of which have eroded less resistant rock.<ref name="naq"/> Where the waterways flow over the escarpment, 16 waterfalls have developed.<ref name="naq"/>
