Generate for me a description of a mystical tunnel carved in the image of a tree trunk with branches, boughs, and leaves.

The tunnel threads its way through a series of rock columns. Each is carved in the image of a tree trunk, with finely rendered bark, branches and an impossibly complex pattern of leaves overhead. Shadows intertwined within the boughs both hide and highlight variations within the carved foliage, yielding a strange effect of movement as if wind is playing through the frozen leaves.
