Write a detailed description of a dreary canyon in the wilderness with a narrow opening, walls, tunnel, leaves, moss, and ground.

Gutted from the mountain by wind and ice, the granite walls of the canyon pinch inward overhead to create scant shelter from the elements. Powdery grey moss dapples the lower surfaces and the ground is carpeted with wind-blown dirt and leaves. Chilly gusts whistle through the narrow opening to the south, carrying a faint scent of pine sap. To the north, the cleft narrows further to form a tunnel leading deeper into the mountain.
