The tunnel was low and tight and curved to the right, and I crawled through the blinding dark, frightened not just of the hunter but of what might currently be in residence in the chamber at the end of that passageway. In the past, when I’d gone exploring there, I had done so with a flashlight, but I didn’t have one this time. The warren offered a home for various species if they wanted it, including rattlesnakes. In the cool of early October, snakes would be lethargic, perhaps not too dangerous, but although Nature’s creatures had spared me all these years, a weasel or a badger or some other formidable animal would be frightened and would feel cornered when I came rushing in upon it. Leading with my face, I was vulnerable, and I shut my eyes tight to protect them from a sudden swipe of claws. The passageway brought me around a corner and into the cave, roughly six feet in diameter and between four and five feet high. Nothing attacked, and I opened my eyes. A silver dollar of sunlight lay in one corner of the room, having fallen through one of the flutes, and a larger and more irregular pattern of light, about the size of my hand, formed under another flute.
