  The Tablelands plateau offers a diverse landscape of lush mountains, green valleys, sparkling lakes and streams, tumbling waterfalls, grassy savannah, endless plains and pockets of ancient rainforest. The Atherton Tablelands encompasses an area of around 64,000km² (25,000mi²) and forms part of Queensland's Great Dividing Range. Source: www.honeymoonguide.com.au/australia/atherton-tablelands.html

  Geological history About 100 million years ago, the eastern edge of the Australian continent extended much further to the east, before tectonic forces fractured the eastern margin, pulling it apart. At the same time, slowly rising mantle material caused a doming up of the continental crust. As the eastern part of the continent broke away, it gradually sank below sea level.[1] Since that time, the uplifted western portion has been slowly eroding westwards, creating the abrupt Great Escarpment, which separates the coastal plain to the east from the uplifted tablelands to the west. From over 4 million to less than 10,000 years ago,[2][3] a series of volcanic eruptions occurred over the Atherton Tablelands. The oldest eruptions created large, gently sloping “shield volcanoes” that produced extensive basalt flows. These flows filled the pre-existing valleys, producing a relatively flat tableland surface, instead of the more dissected landscape that would have existed previously. About one million years ago, the style of eruption changed. The lavas became more gas-charged, throwing fragmented lava into the air which built the numerous, small scoria cones, such as the Seven Sisters, near Yungaburra. Some of the rising magma interacted with groundwater, producing violent eruptions that led to the formation of maar volcanoes, such as Lake Eacham and Lake Barrine. Although all the volcanoes in the Atherton Basalt Province are regarded as being extinct and volcanism has been waning over time, given the relatively recent activity, it is possible that further eruptions could occur in the future.[4] Source; en.wikipedia.org/wiki/Atherton_Tableland
