Boulder

A Boulder is an item in Survival 303.

Overview
Boulders are large stones that occur naturally in ore veins, though they can also be artificially produced by Quarries, mined in any stone surface or crafted from a Rockma Hide. Mining Boulders requires a pickaxe strong enough to mine the ore they reside in, which can severely limit opportunities to mine them early in the game. This can be rectified by travelling to places with high concentrations of stone, like Rockma.

Boulders primarily have their uses in the crafting of Stone Walls for the construction of workshops and are an important step in obtaining modules like the Forge, Workbenches, and the wide variety of stone fortifications available for defending one's settlement.
