The Rock Boulder is a boulder you break with a pickaxe for Stone. The Stone Pickaxe does the job, as it mines both Flint and Stone, and a Rock Boulder can take 9 hits from it before it breaks. Aim at a boulder and the prompt shows its name with a pickaxe icon. If that icon turns red and crossed, the tool in your hand cannot break it.

Horizon has the most Rock Boulder spots nearby, with 34. Sonnenberg's Clinic follows with 23 and the Improvised Radio Tower with 16, while Shattered Convoy and the Water Tower have 14 each. Another 95 spots sit out in the open, away from any named place. The Stone you get goes into the Stone Axe, the Stone Pickaxe and the Stone Shiv.
