The Yosemite Firefall is the phenomenon when the setting sun illuminates the Horsetail Fall waterfall, making it look like fire. The photograph was taken by Sangeeta Dey.
It's good to see that. Not sure when those were taken. For a couple of recent drought years, the firefall was gone and some people said we'd never see it again.
Just checked the website. Those were taken this week! Cool!
