"The sun sets at a certain angle and illuminates the waterfall in luminescent orange and red, making it look like a fluid fire," photographer Sangeeta Dey said in a Facebook post.
"When the fall started glowing, I could not believe what I was seeing. For 10 minutes, all of us sat there mesmerized by this spectacle," Dey said in a post on Instagram. "When it ended, a few of us had tears in our eyes, while some where clapping , and others were just ecstatic to finally get a chance to see it after trying for years."
