This is a moonbow shot that Bob took on the night of May 24, 2021 from Glacier Point in Yosemite National Park. Looking like some kind of frozen confection, Upper Yosemite Falls shows a moonbow in its mist. Focusing in the dark is difficult, so Bob didn't get the sharpest focus on this shot, but it showed the most color of all the photos he took that night.
According to Brian Hawkins of Yosemite Moonbow Predicitions (yosemitemoonbow.com) the appearance of the moonbow in Yosemite Falls as seen from Glacier Point only happens for about 15 minutes and is a broader arc thanks to the fact that you're viewing it from so much farther away than the other vantage points that he does predictions for.
The park was conducting prescribed burns the week Bob was there and Yosemite Valley and Half Dome were almost completely obscured by the smoke from Glacier Point, but, fortunately for him, the smoke cleared out just in time for the predicted appearance of the moonbow.
See our previous post for more information about moon bows.
Oh yeah, and while Bob was at Glacier Point, he met Brian Hawkins who predicts the occurrence of moon bows in Yosemite Falls from various vantage points on his website Yosemite Moonbow Predictions (yosemitemoonbow.com).
Remember, it's not just a picture, it's a story.
