"When I saw the clouds rolling over the mountain, I grabbed my phone as quickly as I could to capture the moment," Hunter told me. "It only lasted a few seconds or so, it was literally like a wave crashing."
Hunter shared the picture on a Facebook Smith Mountain Lake picture group, and the image started making waves of its own. In a good way.
"A local meteorologist saw it and asked if he could share it on the news," she said. "The next thing I know, all the major news outlets are asking my permission to use the photo."
The meteorologist told Hunter the clouds are called "tsunami clouds," but the more formal name for the wave-like clouds is "Kelvin-Helmholtz waves," CNET parent site CBS News reports. They usually form on windy days.
"I knew it was an unusual cloud formation but I had no idea it is so rare," Hunter said. "I was very happy to share it with the world because it is such a phenomenon."
Hunter isn't a professional photographer, but enjoys taking pictures of nature and landscapes as a hobby, noting that she shares them on her Instagram page.
There's also an artsy accent to the cloud formation. According to EarthSky.org, this kind of cloud formation may have inspired Vincent van Gogh's famed painting The Starry Night, the iconic blue and yellow painting showing the swirling sky as the artist saw it from his asylum room in 1889.
