the spine of the world, where two slopes meet and refuse to pick a side
means A long, narrow elevated stretch of land, rock, or other surface, often formed where two slopes meet at the top.
from From Old English 'hrycg,' meaning the back or spine — the same word once used for the bony ridge running down a body. It has Germanic cousins, like German 'Rücken' (back), and the sense gradually climbed outward from the body's spine to the spine of a hill, a roof, or a wave.
