NASA: “The image can be seen in 3 dimensions (3-D) by viewing the following left image with the right eye and the right image with the left eye (cross-eyed viewing).
When stereoscopically merged, the result is a vertically exaggerated view of Earth’s surface in its full three dimensions.
“The Tweed Volcano is one of planet earth’s biggest volcanoes.
Volcanic eruptions lasted about three million years, ending about 20 million years ago.
The volcano basin has been hollowed out by the streams, creeks and river, forming an ‘erosional caldera’.
As the continent moved up the globe the landscape of the whole of Australia became drier.
The original ancient east coast rainforest dried and disappeared, eucalypt trees replacing the rainforest.
However within the Tweed volcano erosion caldera, because of its geology and consequent high rainfall, the original rainforest ecology was protected and survived.
The whole ecological system survived, all of the varied lifeforms, sustained by the ancient rainforest of the caldera. It was all in existence until very, very recently.
We can protect what little is left, and through many organisations and individuals which plant caldera specific native species, help what’s left of the ancient authentic rainforest ecology to survive.
