This sunset from a few weeks ago was pretty spectacular. Drivers were pulling off the highway into the overlook area to get photographs. I overheard one person claiming this was a one-in-a-million sunset. That was probably an overstatement of several magnitudes. More likely, this was a one-in-a-hundred event, meaning you could see a sunset this great a few times a year.
I had been looking at satellite data that afternoon and saw a nice streak of high cirrus clouds moving across northern Arizona. The orientation of the clouds suggested that the sun might briefly appear below the clouds and illuminate the bottoms around and shortly after sunset.
So I headed out to Mormon Lake Overlook where there is a good view of the western sky and waited.
It worked out pretty well.
