Create a brief description of a dreary scene outside a mountain with lichen, a hemlock tree, and a pupa.

The trail becomes indistinct as the vegetation that forms its borders thins. Exposed to the merciless elements, scant foliage grows at this altitude. Patches of colorful lichen adhere to unstable rocks and fallen trees, surrounded by knobby bushes strewn about the barren landscape. Hanging from a skeletal hemlock tree like a grotesque party favor, a silken pupa writhes whenever the biting wind catches it.
