The photo above shows an eye-catching Brocken spectre as viewed while I was hiking the Ampelos massif (Mt. Karvounis)  on Samos Island, Greece. Fog enveloped me on my approach to the summit and suddenly my image was floating in the mist, surrounded by rings of different colors. Diffraction of sunlight in minute fog droplets is responsible for this phenomenon, which is often seen in mountainous terrain when clouds form below the level of the observer. This shot was taken near the summit of Mt. Karvounis, at approximately 3,445 ft (1,050 m), on November 18, 2017.
