Coal in Permafrost

A Coal Boulder is a boulder you break with a pickaxe to get Coal. Aim at one and the prompt shows its name with a pickaxe icon. The Stone Pickaxe will not do the job: with it in hand the icon stays red, and 3 hits leave the boulder's bar full. You need a Flint Pickaxe, whose tooltip names Sulfur, Copper, Coal, Flint and Stone as what it mines.

The map has 163 Coal Boulder spots. Sonnenberg's Clinic has the most nearby, with 16. Horizon and Shallow Rift follow with 12 each, and Landscar Cave and the Improvised Radio Tower have 9 each. Another 73 sit out in the open, away from any named place. Coal goes into Copper Ingot, Iron Ingot, Moonrock Ingot and Gunpowder.
