The Brocken Spectre, as captured by Michael Burke in June 2009. Michael was atop Carrauntoohil at the time – the highest peak in Ireland, located in County Kerry. He was gazing toward Caher, Ireland’s third-highest peak. Notice Carrauntoohil’s shadow, cast on Caher.
The Brocken Spectre is your own shadow, cast on mists below you, when you are mountain climbing. The shadow may appear enormous and has a ring around it.
