The panorama above features Laguna Verde in Chile, a salt lake lying 14,200 ft (4,350 m) above sea level in the central Andes. It's rimmed by some of the highest volcanoes in the world, with the 19,300 ft (5,900 m) Cerro Laguna Verde visible in the background (left-center). Its waters are being replenished by ice and snow melting on the surrounding mountains and by geothermal springs. The turquoise color of the lake comes from algae that live in it and perhaps from suspended sediments as well. Note that on the right, above the cloud deck, the Milky Way can be seen, while at left the zodiacal light is evident. Panorama taken on August 5, 2014.

Photo Details: Composed of multiple images; taken with a Canon 6D camera; Samyang 24mm 1.4 lens; ISO 3200; individual exposures each 25 seconds.
