This photo was taken September 22nd, 2025 at 9:55am MDT. This was taken near the parking garage by the CU Boulder engineering center at 40.00733°N, 105.26000°W, while I was facing Northwest (as can be seen from the pre-cropped image). The lower section of the clouds appear to be stratocumulus, while the higher portion of the cloud appears to be altocumulus and lenticular clouds. The atmosphere for this cloud appears to be slightly unstable.
