–part 5 of the essay One year on Mt. Wendelstein–

Sometimes, things can happen that are hard to explain for a moment. Here, not only did I see a mountain shadow, there appeared to be an inverted shadow above it, forming an hourglass-like structure. One can even see a small color change between the upper shadow and its surrounding area. What happened was that there was metereological inversion behind me and light reflected away from the clouds, slightly changing their infrared color as seen here and creating this inverted second shadow.
