The tunnel descended towards the inside of the fell. I noticed that the metal pipe ran along its length. I had no space to walk with my back straight, and my father’s head brushed the ceiling at times. The rock under our feet was unexpectedly smooth. The light of my lantern clung to the creases on the back of my father’s jacket and the darkness clung to the dents in the walls. I listened to the silence of the earth around us, different from the silence above the ground: denser, stiller. And slowly I began to distinguish a stretching, growing sound at its core, familiar and yet strange. I had never before heard it flowing free, entirely pushed by its own weight and will. It was akin to sounds like rain knuckling the windows or bathwater poured on the roots of the pine trees, but this sound wasn’t tame or narrow, not chained in man-made confines. It wrapped me and pulled me in, until it was close as the walls, close as the dark.
