In this photo taken by family member mountain shadow seems to be sandwiched between the mountain and the Sun. The Sun was located behind the clouds on the south side of the mountain at around 4 P.M. (38 degree latitude, Atlantic Ocean). See the rays shining up behind the clouds? There's also a small "diamond" at the tip of the mountain, which could be the Sun as well or Sun's reflection. Now if the Sun was located on the right side of the photo (West) the mountain would be lit up, right? Some mimnutes later the shade has disappeared after the clouds dissipated. What could this be and how is it formed?
