Sunsets are a regular theme for photographers since they provide a scene that resonates with people.  I have shot plenty of them myself.  However, while on Orcas, I saw something in the sky which I was quite baffled by and taken with.  The sun was setting in the west and, looking off in that direction, the sky was lighting up as you would expect.  However, looking directly south, the sky was doing something very odd.  I don’t know exactly what was happening but my guess is that there was a lot of moisture in the sky in that direction and it was reflecting the setting sun back in our direction.  It was a localized effect and quite something to see.
