Hum, I am not sure what I am seeing in this picture. I took it yesterday mid morning from my house looking SW towards Ragged Mtn. It was still very cold down below and it looks like there was a weak inversion. The "cloud" at the base of Ragged was there for awhile and changed shapes. It almost looks like their snowmaking guns were producing snow that was drifting down the mountain and settling near where the lodge would be.
Any guesses?
Edit: I really zoomed in. Perhaps they were just taking advantage of the -10F and making snow along the trails at the base of the mountain
