Wjmdronie used a DJI Phantom 4 drone to create this epic aerial view of a well known dam in Switzerland. Émosson Dam is situated in the Valais canton in the southwestern part of the country, close to the French border. It was completed in 1974, after a seven year construction period. The dam is powered by runoff from several glaciers in the Swiss Alps, which are channeled to the dam through a valley. The dam necessitated a Swiss/French land exchange to keep it entirely on Swiss territory.
