Some perfect swell out here in Colorado last Sunday. This was shot around 7:30 in the morning on 3/10/13. I’ve never seen clouds like this before and I was blown away as I came up I70 around Genesse Park and Evergreen only to see this incredible cloud formation stretching the length of my vision. It’s been explained to me that this kind of cloud sometimes occurs when the temperature rapidly decreases from very warm to very cold. Case in point the day prior to this had been in the high 60s in Evergreen and overnight the temperatures dropped to the teens. Hope you enjoy. I’ll have some more new photos soon.
