Tweed Valley, NSW – “The Tweed” – is a dramatic looking 30km-or-so-wide part-caldera characterised by a central 1,152m peak, Mount Warning.
On historical maps Mt. Wollumbin (Wolumbin) is marked in Eungella, just NNW of Mt. Warning (Wulambiny (bush turkey), with momoli (nest) meaning the caldera). Some confusion currently exists due to the similarity of the names and lack of local indigenius advice(?)
The Tweed is most often described in geological terms as the eroded remnants of an ancient, massive shield volcano – an interpretation of the Tweed Valley’s morphology which leads to some perplexing questions. In the light of the latest understandings of planetary geography however, plasma discharge scarring does create forms similar to those found in local topographies.
For the magma/gravity/erosion approach some obvious questions are,
- How does water erode a valley floor like the NW Tweed Valley floor, flat? Water leaves channels.
- If water did wash away the entire volume of a huge volcanic cone down into the Tweed Valley that we see today, why do the monoliths on the plain like the one beside Eviron Rd – or the impinging ridges closer to the sea and presumably downstream not display any noticeable extra erosion on their ‘upstream’ flanks?
- How could water have eroded the North and Northwest walls of the Tweed Valley, including the amazing Limpinwood Valley and so on, and not left massive holes, drainage channels?
- How does vulcanology/erosion explain so many symmetrical and regular topographical features on and around Mount Warning itself and around the Tweed Valley generally, and indeed throughout the entire McPherson Range?
Marked-up Google Maps showing prominent regular features in and around the Tweed.
In the image below ridge lines are highlighted extending radially around Mount Warning, while its surrounding ‘shield-like’ upper ridges form coherently organised regular curves.
The northwest of Main Range displays a series of lichtenberg-figure*-shaped ridges and valleys, and forms a regular curve extending SW exactly through the southern edge of the Mount Barney caldera (circled) and directly via a ridgeline to the Tweed Caldera rim. Inside the Tweed Valley, a vertical yellow line marks a series of geomorphic features extending through twin parallel fractures on Mount Warning’s peak over parallel raised ground terrain on the northern Tweed Valley floor, extending over the valley wall into the Springbrook N.P. and northward as a lichtenberg ridge system extending about 30kms to Ormeau, the Gold Coast hinterland hills.
The other line marks land features through a large gap in the SW caldera wall along the path of the Tweed River between the elevated Hattons Bluff and Mount Nullum, and out across the remarkably flat plains to the coast, to Fingal.
In this picture the circled Mt. Barney caldera is directly connected via the marked (obscured) ridge line from its ‘caldera’ rim to another ridge leading up to the rim of the Tweed caldera.
Very lightly circled are two areas adjacent to that connection where the rim extends into the valley. The southern highlighted area is The Pinnacle and can be walked out onto**, and the northern triangular rock formation is Limpinwood Nature Reserve. The line on the right is a re-iteration of the ‘fracture lines’ pattern from the tip of Mt. Warning across the valley floor and into Springbrook N.P an so on.
Obviously over enormous time scales ‘anything can happen’ in the forward motion of geographical processes. That means we have no idea. However the topography of the Tweed includes many symmetrical patterns and regular shapes besides those illustrated above, indicating that perhaps more than lava and gravity were involved in the formation of its landforms….
At thunderbolts.info, the role of electric charges in nature is discussed quite comprehensively, and this archive of articles on ‘plasma geology’ may help to make contextual sense of the obviously highly energetic and enigmatic landforms of the Tweed Valley N.S.W. and surrounds.

These images from Google Maps show lichtenberg shapes pervade the Tweed and Main Range topographies, and indeed the entire McPherson Range quite spectacularly although there is no known explanation relating to tectonics / vulcanism / erosion for such land forms.
Hypothesis: The whole McPherson Range is the result of a northward roaming plasma discharge, wherein the up-draw of ions (Amps) was of such force that it lifted the crust, energetically forming the various elements of the Range. The discharge may well have terminated laterally at Mt Barney, leaving the Main Range and Tweed Caldera/Mt Warning and from it the Gold Coast hinterland range as final exclamations.
Topographical aspects of the McPherson Range that appear to support this hypothesis are:
– the prevalence of lichtenburg and dendtretic lines throughout the topography of the range,
– symmetries occurring in various landforms throughout the range,
– the meandering path of the range,
– well-defined angular shapes in land forms,
– extraordinary land form features displayed at Carrai NP, Oxley Wild Rivers NP, Cunnawarra NP, Collah Tops NP, Tweed caldera, Mt Barney, the incredible scalloped northern boundary of Dorrigo NP and New England NP, I could go on – the topography of the whole Range is replete with complex symmetries in fairly sharp relief.
Images of plasma discharge scarring on solids like metal balls can be looked up on Google images, and compared to land form shapes. Anyone can look up Google or other terrain and satellite maps to confirm the existence of the above-mentioned features.
Many remarkable topographical features tend to support a view incorporating some kind of terrestrial-scale electrical discharge across an earthly, Aussie anode as being the cause of the remarkable McPherson Range. Obviously expert research needs to be examined and even done before an electrical hypothesis can be fully confirmed.
Conclusion: The McPherson Range appears to be a terrestrial plasma discharge scar. I would like to invite an open source research focus to further investigate this view…
