We are booksellers in Tucson, Arizona that specialize in books on the Natural History of the Desert Southwest, Nature, Western Americana and Native Americana. The name GreenFire originated with the words of Aldo Leopold from his book A Sand County Almanac We reached the old wolf in time to watch a fierce green fire dying in her eyes. I realized then, and have known ever since, that there was something new to me in those eyes-something known only to her and to the mountain. I was young then, and full of trigger-itch; I thought that fewer wolves meant more deer, and that no wolves would mean hunters' paradise. But after seeing the green fire die, I sensed that neither the wolf nor the mountain agreed with such a view.
