Reverse Snow Line

The snow line usually marks the elevation above which there is snow, often forming snow-capped mountains. On this morning, the snow line was below the mountain top.
I had just spent two hours in the tractor cab taking care of snow removal duties and was then able to concentrate on capturing some fresh snow images. My studio overlooks a valley and a small mountain ridge. The snow came with a strong wind from the opposite side of that ridge and above the ground line, the windswept trees remained bare while the lower elevation trees, protected by the mountain, were heavily snow-laden. The snow/no-snow line was strong and I was drawn to the contrast.
The mountain was roughly 1,500 yards (1,500m) away and I could see over a mile (1.6 km) of it in width. This meant that the primary interest for me was strongly horizontal. I could photograph using a wide angle focal length and crop the top and bottom off to get just the strong line of bare trees over the snow line, I could capture multiple frames at a longer focal length to later stitch into a panoramic image or I could go with a telephoto focal length and frame tightly. I chose the telephoto lens option and began isolating specific areas of mountain.
My lens choice was the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens and mounted it to the being-reviewed Canon EOS M5 via the EF-EOS M Adapter.
The storm was clearing and periodically, the sun was shining through breaks in the clouds. The areas of snow in the direct sunlight became especially bright and the partial illumination created additional interest within the already interesting scene. When available, the partially lit portions of the scene were my focus.
Often, photographing scenes this far away results in details being strongly affected by heat waves, but on this crisp, clear morning, the M5 behind the 100-400 L II delivered very sharp image quality, even at this distance. Notice that photographing subjects from very long distances always results in a compressed look with less perception of depth (trees farther away appear similarly-sized as closer trees). This attribute can be good or bad depending on the scene, how the composition comes together and the viewer's taste.
While the circular polarizer filter was not making a noticeable effect, I had it mounted in case blue sky opened up and I note its use for those questioning the exposure settings.
