That's the so-called "Gateway to Hell," right?
If such things existed on Avalon, I imagine they would have been hotspots (no pun intended) of tribal warfare, especially given that they would be exceedingly rare: Avalon is mostly covered in water ice, I believe, with an ocean of liquid water below. Exposed rock would be rare. That's another strike against metallurgy on Avalon--lack of places to mine.
