Bright Cantaloupe highlights in the bright precipitation of these stratus clouds, and Halloween orange colors on the fading rain at right of the frame. Silhouetted bare ridges in the lower quarter, under these clouds that darken in as time progresses, the open sky a perfect Mid-blue.

The scientific adage of ‘what goes up, must come down’ rings true in this scene where, at right, lower-level clouds rise in convection. Over this ridgeline, there are pockets of air that fall through the cloud as cold patches, creating these distinctive looking clouds. While the dire, dark gray, bizarre looking ‘mammatus’ are this size only 30-40000 ft and attached to monstrous storms, these are clearly harmless clouds.

Low clouds are attempting to build on the Grand Tetons in the early daylight. The peaks are low on glacial ice, due to late summer.

Motion controlled tripod in Rocky Mountain National Park on a partly cloudy day looking east, then south from a viewpoint.
… Backlit by the sun making stark contrast, undulating. These low-level clouds move along a wind left-to-right, transforming as they go. Stark backlighting is necessary when capturing crepuscular rays and shadows to preserve highlights. Two or three separate bands of cloud are evident in the lower half of the frame, the largest of which show signs of nearing future precipitation, with the upper half containing smaller patches of varying density overhead. Length at 30 fps: Seven seconds and nine frames.
… the slopes and loiter on almost no wind. One may assume on first viewing a few seconds of watching the stratus is inevitably going to override the sky, but that does not happen; instead, the clouds are caught and created on the mountain peaks. Four snowy peaks, with one dominating the left quarter, in deep snow, are intermittently covered. The other three have sheer faces too steep for any snow to cling to. The light turns pinker as time moves on.
