"Long, blue, spiky-edged shadows crept out across the snow-fields, while a rosy glow, at first scare discernible, gradually deepened and suffused every mountain-top, flushing the glaciers and the harsh crags above them. This was the alpenglow, to me the most impressive of all the terrestrial manifestations of God. At the touch of this divine light, the mountains seemed to kindle to a rapt, religious consciousness, and stood hushed like devout worshippers waiting to be blessed." - John Muir (The Wild Muir: Twenty-Two of John Muir's Greatest Adventures)
