Just as the sun rises over Lake Hintersee in Germany’s Berchtesgaden National Park, an eerie stillness hangs in the air. The “dead calm” of this winter sunrise gives “a mystic view of the mountains greeting the morning sun,” writes Your Shot photographer Gregor Thelen. “The quietness and peace is tangible in the delicate shades ... rising from the night.” The park, in Germany’s southeastern corner near the Austrian border, has been a UNESCO Biosphere Reserve since 1990 and is the oldest conservation area in the Berchtesgaden Alps.
