A stitch in time - Panorama of a slice of geologic time, the Grand Canyon
Watching darkness spread over the canyon, you see more clearly than in full daylight which are the highest points and what are the spatial relationships among the various fins, peaks, buttes, ridges, etc.

A few words about leveling or straightening photographs of this part of the world. There are two very large problems with using features in the photos themselves as references. One is that the Colorado Plateau itself is not level. Using a distant horizon can be misleading. The other is that in viewing the Grand Canyon, very rarely are rock faces in which there are strata which might be roughly level oriented in planes parallel to the camera's focal plane. It becomes a big guessing game. I use a spirit level mounted to my camera, but don't always remember to check it. My guess is that this panorama is a few degrees off level, but not more than that. I chose not to make any further adjustments, since that always produces loss of the image content.
