Ennie Award for Best Cavern Map goes to... Fire Ants.
One of the staple RPG tropes is the "Bug Hunt", we've all done them. There are some pretty cool bug hunt tunnel maps out there, but even the best human cartographers can't come close in complexity to these real world Fire Ant Colonies. These stunning aluminium casts are the work of anthillart.com
Fire Ant Colony #45 - 18.5"x12.5"x13" (HxWxL)
Carpenter Ant Colony #31 - 16.5"x4.5"x8" (HxWxL)
The artists YouTube channel has some interesting videos showing the whole casting process which inevitably causes the destruction of the colony. I'm rooting for Hicks and Hudson on this one and prefer to immortalize the work of these pests rather than go down the "nuke it from orbit" route.
