The first blast of steam arrives like a punctuation mark: a column of boiling water launching from Old Faithful into a cold Yellowstone sky. Around you, boardwalks stitch across bleached ground, and the air tastes faintly of iron and sulfur. Visitors fall into a hush—phones up, audio cued—while an invisible narrator begins to fill in the scene: why one pool is electric blue, why another moans and sputters, and how a planet’s heat pushes up through fractures and ancient rock.
