“As I ascended, I realized I didn’t understand what a mountain was, or even if I was hiking up one mountain or a series of them glommed together. I’d not grown up around mountains. I’d walked on a few, but only on well-trod paths on day hikes. They’d seemed to be nothing more than really big hills. But they were not that. They were, I now realized, layered and complex, inexplicable and analogous to nothing. Each time I reached the place that I thought was the top of the mountain or the series of mountains glommed together, I was wrong. There was still more up to go, even if first there was a tiny slope that went tantalizingly down. So up I went until I reached what really was the top. I knew it was the top because there was snow. Not on the ground, but falling from the sky, in thin flakes that swirled in mad patterns, pushed by the wind.”
