I've shot this formation before on several occasions. I drive by it semi-regularly and yesterday I was returning from a photo hike into a canyon and saw the lake as glassy as I ever have. It was 3pm and dead calm and about 40 degrees which is downright weird for here this time of year. I didn't have to hurry back and I had my photo gear with me so why not shoot some frames? The highs in the first week of January are typically in the single digits and it would usually only warm a little up to snow.
This is two images stitched with MS ICE.
