unsurmountable
Impossible to conquer
Unsurmountable means impossible to overcome or get past—an obstacle that cannot be surmounted.
The word is a less common variant of insurmountable, carrying the same meaning: The challenges seemed unsurmountable at first.
Both forms describe barriers, difficulties, or problems too great to conquer.
