It’s What Rock Am I Wednesday!

.

Can you guess what I am?

.

The Discovery Voyager team visited me yesterday, so I have to be in northern NSW. Actually, I am on Gamilaroi Country, and you might have heard George the Geologist talking about rocks just like me at Ebor Falls recently.

.

I am made up of incredibly regular hexagonal columns that have a history of more than 20 million years, and I am part of a larger volcanic landscape rising out of surrounding agricultural land.
