A flock of sheep crosses alpine terrain in Flaesch, Switzerland, Tuesday, August 6, 2019, under the “Falknis” peak (2562 meters above sea level). During the so-called “Schafuebergang”, 1500 sheep wander from one meadow to the other, crossing on a steep, narrow alpine trail. (Photo by Gian Ehrenzeller/Keystone via AP Photo)
