If we were doomed to live forever, we would scarcely be aware of the beauty around us.

There's an elegiac quality in watching [American wilderness] go, because it's our own myth, the American frontier, that's deteriorating before our eyes.

The sun is roaring, it fills to bursting each crystal of snow. I flush with feeling, moved beyond my comprehension, and once again, the warm tears freeze upon my face.
