the dreamy blue haze

Characteristic, too, is the dreamy blue haze, like that of Indian summer intensified, that ever hovers over the mountains, unless they be swathed in cloud, or, for a few minutes, after a sharp rain-storm has cleared the atmosphere. Both the Blue Ridge and the Smoky Mountains owe their names to this tenuous mist. It softens all outlines, and lends a mirage-like effect of great distance to objects that are but a few miles off, while those farther removed grow more and more intangible until finally the sky-line blends with the sky itself.

The foreground of such a landscape, in summer, is warm, soft, dreamy, caressing, habitable; beyond it are gentle and luring solitudes; the remote ranges are inexpressibly lonesome, isolated and mysterious; but everywhere the green forest mantle bespeaks a vital present; nowhere does cold, bare granite stand as the sepulchre of an immemorial past.
