Mount Everest (8848m), Chomolungma, bathed in the glow of the sunset sky. Imaged by Tamas Ladanyi (site) of Hungary from the peak Kala Patthar (5545m). Image ©Tamas Ladanyi, shown with permission. At sunset and for a while beyond the bright western sky near the horizon, the "twilight arch", suffuses high peaks with a soft orange yellow light. As twilight progresses the colours shift to purple. Stages of the light are called the "Alpenglow".
