You're right. You could use that hour to do anything you wan't and say that this video is a waste of time but yet you're still here posting in this thread. The same goes for me btw, I have some spare time now, as I'm between jobs and there's no shame in that. But don't come up with the excuse of lack of time or anything, because clearly you have the time to browse these forums.
You're right, I'm no volcano expert and I told you before, I don't know much about em or lava. But there are things that are pretty clear and understandable just from looking at them. I may be wrong, I know, but to me these beautuful hexagon formations do not look like they were created by a volcanic eruption. It looks too perfect.
And to answer your questions:
I think it is. Just not by Lava.
And btw, if you feel like I don't answer everything or write like a retard, it's simply because English is not my first language. So pardon me.
