The Iron Boulder is a boulder you break with a pickaxe to get Iron. The Flint Pickaxe will not do it: its tooltip covers Sulfur, Copper, Coal, Flint and Stone and stops there, so you need a better pickaxe. Aim at a boulder and the prompt shows its name beside a pickaxe icon. If that icon is red and crossed, the tool in your hand cannot break it.
Sonnenberg's Clinic is the place to head for, with 56 spots nearby. Rat Queen's Crossing follows with 15 and Shallow Rift with 10, while Horizon and the Solar Power Plant have 3 each. Away from any named place, 103 spots sit out in the open, so you can pick up Iron between destinations as well. The Iron goes into crafting Iron Ingot and Quality Metal.
