Previously, when Saruman’s doppelganger couldn’t forcefully tunnel up the mountain, he ordered the orcs to gather snow from faraway; heating the snow into water, then hastily transporting the water before it had the chance of freezing. Using the water, they slowly condensed and sculptured its way up, to forge a path leading to the summit.
Although much effort was created, sacrificing countless frostbitten orcs; this form of paving a way to the snowy peak was undoubtedly more effective, and efficient than forcefully gnawing a pathway up.
However, cementing an artificial ice road up contained a massive underlying danger. It was clear that the artificial ice road was evidently weaker, completely incomparably to the ancient density of the primary ice layers of the snowy mountain.
