The bus slips out of Reykjavík before the day has fully opened, headlights tracing the black lava fields while steam hovers like a promise over distant hot springs. By the time you reach Þingvellir, the air is sharp and clear; the plain opens up and the rift between continents is impossible to ignore. You can stand with a foot on either side of the Mid-Atlantic Ridge and feel the patient push of geology that shaped this island.
