What?

A bad joke from Spinal Tap.

If it was a mystcraft world it might be the sky biome, it sometimes does stuff like that.
Since it's not, I would say IC2 terraformer. Is this ssp or smp?

Looks like a terraformer with a Flatificator TFBP in it caused that, its probably at the level of the dirt on that cliff. Which would make sense if that is on a server as someone may of tried to fill the canyon in which takes a insane amount of time/power.

Do Terraformers even have anywhere near that much range?

 

[Vovk]

I am super curious and the picture seems to be gone :c

Looking at the wiki that TFBP has a range of 20x20 meters or more.

Confirmed it was a terraformer
