Sometime ago I mentioned my favorite view on the island of Maui is the 30 mile shadow of Haleakala at sunset. This past year when I visited I was treated to an interesting display of anti-crepuscular rays converging on the horizon. This happened just before sunset and the perspective effect of the rays converging on the horizon was quite a mind bender. Remember this was seen with the sun to my back as the beams of light made their way around the gigantic Haleakala volcano. The next time you’re watching sunset don’t forget to look behind you.
