Establish a recoverable Deep North foothold
Quick answer
Approach unexplored far-north terrain with a tested way home, land before committing cargo, and build a minimal fallback on cleared stable ground. Deep snow can prevent building and frozen water can betray your footing. Treat the Snow Shovel and Grappling Hook as useful tools when your current crafting menus expose them, but do not postpone a careful scout solely because their exact unlocks are not established here.
