Lightning Strikes The Granite Belt is one of the most lightning prone areas in Australia. On a small hill behind the homestead is a tree which was recently stuck by lightning. Normally this is a catastrophic event for the tree and usually results in it being slit in two. In our case the tree below was struck by Lightning.

Interestingly you can see where the lighting struck the top of the tree, and then made it’s way to earth and stripped about 10 cm wide path of bark off. Fragments of bark were found 20m away from the tree, impaled into the ground. At present the tree is still alive.

The bark is removed from a branch at the top if the tree.

On it's way down it has severed this large limb, which fell to the ground below.

I’m not sure why such a large limb was broken off, when smaller limbs along the path are intact (except for the loss of a strip of bark). One thought is maybe the limb was the primary point of impact and then the current discharged up and down the tree. Anyway maybe a lighting expert can tell us.

I used to live on Amiens Road, and remember often looking North to the amazing electrical storms. That, the names of the nearby towns, and the anti-hail cannons going off on one Armistice Day brought to mind what it might have been like in No Man's Land those many years ago. I note your post was made on Anzac Day.

Great pics.

I dunno if it's strictly an OZ-ism, but just in case, for non-OZ readers, (nihao `}, such fallen branches are called widowmakers, for obvious reasons.

It's a magic part of the world you are in there.

Keep an eye out for specimens of Border Boronia, ( Boronia repanda ), related to Granite Boronia. B. R. is an endangered species.

Here's a picture

I don't know about this one, but other boronia's are famously perfumed.

It occurs in the Cotton Vale, Thulimbah, Passchendaele and Stanthorpe districts with a range of less than 20 kilometres...in sandy soil among granite outcrops, in rocky crevices and scree, associated with the rare Grevillea scortechinii. Careful with those boots Eugene.. apols to Pink Floyd.


More Good Luck to you.
