Write a detailed description of a chilling scene outside a glacier in the wilderness with ice, glacier, and tundra.
assistant
The makeshift trail that leads back to the tundra comes to a halt at the bottom slope of a gigantic glacier, dwarfed only in size by the mountain itself. Further up the glacier, the going gets even rougher, with piles of rock frozen in place to mark the way across the ice. Deep rumbles shake the ground as the ice grinds its way down the steep grade.
