Taken from a four picture series by artist/photographer Amelia Bauer, the cover is a close crop of the 4th one shown below. Something about seeing trees in perfect nighttime blackness illuminated by an intense light speaks to me on a subconscious level I can't quite explain. Glance at, say, the 1st one below and you might mistake it for a quick shot of one of the Ents from the Lord of the Rings movies. Glance quickly at the others and you might assume this a photograph someone took of Bigfoot and now you need to look closer to spot him (or her!).
