The Moonrock Boulder is a boulder you break with a pickaxe for Moon Rock. The Flint Pickaxe will not do it: its tooltip stops at Sulfur, Copper, Coal, Flint and Stone, so you need a better pickaxe. Before you swing, aim at the boulder. The prompt shows its name with a pickaxe icon, and a red, crossed icon means the tool in your hand cannot break it.
The map has 54 Moonrock Boulder spots, and most of them sit close to named places. Sonnenberg's Clinic has the most nearby with 16, followed by the Crater with 13 and Shallow Rift with 7, so these three make the best targets for a trip. Bunker Checkpoint has 5 nearby and the Military Area has 3. Another 6 spots lie out in the open, away from any named place.
