Cumulus cloud (stable atmosphere since CAPE = 0 ), taken on September 20th, 2021 at 4:06 PM from the 11th floor of Gamow Tower in the Physics department at the University of Colorado – Boulder facing northwest towards the front range. I liked the minimalist effect of the clouds in the otherwise clear and beautifully colored sky along with the green mountain that is also seen in the photo. Stats: Canon Rebel T7, 1/200, f/ 9, 49 mm, ISO 800
