Wollumbin, Mt Warning and the Tweed Shield erosion caldera.

The following is from paragraph 3 in the Statement of Outstanding Universal Value about the World Heritage place Gondwana Rainforests of Australia, relating to geological formations, addressing Criterion viii;





The Tweed Shield erosion caldera.  The central peak, a volcanic plug immediately above here, is called Wollumbin or Mount Warning, it is 1157 m high and is just one part of this very significant geological feature, Wollumbin is thought to have originally have been about 2300 m high according to the plaque at the end of this platform.

This panoramic image was created from a video I took on Tuesday 9 August 2011, at a viewing platform off the Tweed Range Rd, The Pinnacle Lookout, we were on our way out of the Border Ranges National Park.  From The Pinnacle Lookout to Wollumbin, just off the end of the right hand railing, is 13.4 km and it is generally over 30 km from one side of the Tweed Caldera to the other but that is just the eroded bits, the edges of the parts that are now gone.

Using Google Maps the location of The Pinnacle Lookout is -28.40299,153.134472  If you do have a look at is location zoom out and you will see the planezes, these are a series of triangular facets facing outward from a conical volcanic peak (this one used to be bigger). The planezes are separated by radiating streams which run down the flanks of the cone. The planezes extend from behind Byron Bay to behind the Gold Coast and quite some distance inland.

The tiny image above does not do this massive feature justice.  I strongly recommend viewing the image full screen using the full size image, 3.5mb, which is at http://sassafras.id.au/images/Wollumbin_stitch.jpg it may be necessary to click the browser image to view it larger.  Pan across the image with your mouse or finger.

Technical info.

The video was captured by a Sony Handicam HDR-CX110 on 9 August 2011, I used a tripod. On 19 May 2013 I converted it to a still panorama photo using the free Microsoft Image Composite Editor (ICE).  The image was created by Paul Segal and is licensed under a Creative Commons Attribution-NonCommercial 3.0 Australia License.

I stopped about half way through the panning and chatted about Wollumbin, the video camera jiggled a little, hence the black strips on parts of the top and bottom of the image.  I wanted all the image so I didn't crop them out.
