This photo was taken in the University Hill area, west of the CU Boulder main campus (1339 Broadway, Boulder, CO 80302; 40.0°N, –105.28°W), facing the northwest.
The cloud deck visible in the image is an lenticular-type cloud covering nearly the entire sky, characterized by its smooth and uniform underside and clear boundary. Based on its structure and the skew-T figure, the atmosphere at the time was stable.

Very crisp cloud image. This image is similar to mine and it seems this is an orographic formation (caused by topography like mountains). I also really enjoy how the cloud ends uniformly and you include the colorful fall tress below. Great image!
I know that some people might not like the traffic lights, but I like how the beam they’re mounted on lines up with the cloud front. The lights and trees add some great color as well – by themselves, the altostratus clouds can be kind of plain because they’re so smooth and white.
