The van rumbles off the Ring Road and the landscape changes. Black ash fields give way to moss-matted ridges and, soon, to braided rivers that dare the tires forward — clear glacial run-off one minute, silt-laden brown the next. By the time the vehicle pulls into the hollowed green of Þórsmörk, the air feels colder and cleaner, the sky framed by jagged ice rims. You step out not on a manicured trailhead but into a place shaped by fire and ice: volcanoes upstream, glaciers on either side, and rivers that redraw the map every year.
