The 3-way fight for a 1,800km long mountain ridge under the Arctic

I'm the author of this piece. Since a few of my geology stories were very kindly received on here a while back, I thought I'd give this a go, with the hope I'm not being spammy in foisting my own stuff upon you all. Cheers for taking a look - and it's a pretty remarkable natural feature which I previously knew nothing about (if it was laid across Europe, it'd run from London to Belgrade).
