Steam drifts from a natural geothermal cavern carved into pale mineral-rich rock at Wai-O-Tapu. The rough edges and layered textures reveal the slow work of heat, water, and chemical reaction beneath the surface, while faint vapour escaping from within hints at the volatile activity below. The image captures a quieter, more mysterious side of the geothermal landscape, where erosion and pressure shape the land over time.
