Morning light in Mexico City gives way to an ascending hum as a minibus threads west toward the Sierra. By late morning the highway falls away and the air sharpens — the forest begins to smell of damp earth and resin. At Piedra Herrada, the oyamel firs lean close and the monarchs hang thick under branches, their orange wings like weathered flags that refuse to stop moving.
