It's the least of your worries then...

It's not now nor ever has been a volcano of any type so we can't call it 'extinct' as it was never 'active'...
So Exon that means it's not extinct! You'd better panic...

It's a great question and the thread has given some brilliant answers. Interestingly, I distinctly remember our primary school teacher telling us that the Sugarloaf in Wicklow was an extinct volcano...goes to show you the quality of my primary school education

There are loads of Sugarloaf mountains.

There are two in Wicklow alone.

For three centuries sugar was imported into Europe as pyramidal "sugar loaves".

The mountain shape was named after them.

As in Rio.

There are 3 in Wicklow alone. The two by Bray, and the third is in the Glen of Imaal.

I was told its a dormant volcano!!

As someone who grew up in Bray, my whole world has been turned up side down. I have to question everything now, including anything else my 2nd class teacher taught me.
Is the river Dargle still the longest river in Ireland?

A carboniferous volcano is Croghan hill in the midlands, or up north past the border.

How do we go about setting up a Geology subforum?

I've been trying to set up and Environmental and Earth Sciences sub-forum for the last while. I know it's not strictly 'Geology', but I can't see why this kind of discussion couldn't be accommodated for. I've found this thread very interesting and it again highlights the need for an Earth Sciences type sub-forum.
