PIX4675989: Tyndall Glacier, Chile - Tyndall Glacier, Chile - The Tyndall Glacier in Torres del Paine National Park in Chile, observed from the International Space Station in November 2007. Tyndall Glacier is located in the Torres del Paine National Park in Chile. This glacier, which has a total area of 331 square kilometers and a length of 32 kilometers (based on 1996 measurements), begins in the Patagonian Andes Mountains to the west and terminates in Lago Geikie. The digital astronaut photograph taken in november 2007 records visible light in red, green, and blue wavelengths (true color). The Tyndall Glacier terminus has retreated significantly during the past 17 years. Significant ice loss was also observed earlier this year at Grey Glacier, about 30 kilometers to the north - northeast, suggesting both glaciers are responding similarly to regional changes in temperature and precipitation. A medial moraine is visible in the center of the glacier, extending along its length (top image, center left). Moraines - - accumulations of soil and rock debris - - form along the edges of a glacier as it flows downhill across the landscape (much like a snowplow builds ridges of snow along the roadside). Glaciers flowing downslope through adjacent valleys merge when they encounter each other, and debris entrained along their sides becomes concentrated in the central portion of the new combined ice mass, much as small streams join to form a river.Crevasse fields are also visible in the image. The crevasse - - small, but potentially quite deep fissures - - form as a result of stress between slower - and faster - moving ice within the glacier. Crevasse fields on Tyndall Glacier are most evident near rock promontories extending into the glacier; these rock outcrops cause the ice to slow as it flows around the obstruction / Bridgeman Images
PIX4676015: Chuquicamata Copper Mine - Chile - Chuquicamata Mine - Chile: The Chuquicamata Mine in Chile is the largest open-air copper mine in the world. Located in the Atacama Desert in northern Chile 15 km from the city of Calama, this mine alone contains 13% of the world's copper reserves. Image taken from the International Space Station (ISS) on December 9, 2009. This open-pit copper mine is one of the largest ones in the world.

PIX4676142: Laguna Cejar - Desert d'Atacama - Chile - Cejar Lagoon - Chile - Reflections on Laguna Cejar, a dirty water hole located about 20 km from San Pedro de Atacama. August 2014. Salar de Atacama's Cejar Lagoon is a giant sinkhole, the dark blue is actually super deep water. It has a salt concentration that ranges from 5 to 28%, producing at the higher end of the range an effect of floating like the Dead Sea / Bridgeman Images

From left to right, Fernandina Island, Isabela Island (with volcanoes Wolf, Darwin and Alcedo), and Santiago Island. North of the Galapagos' largest island, Isabela, where several volcanos appear. From the top to bottom are volcano Wolf, ranking among the archipelago's most active volcanoes, Darwin and Alcedo. To the left of Isabela is Fernandina island, at right is Santiago island.

PIX4676455: Toquepala Copper Mine - Peru - Toquepala Copper Mine - Southern Peru: The Toquepala mine in southern Peru is a large open-pit copper mine. Image taken from the International Space Station (ISS) on 22 September 2003. The rugged, mineral-rich Andes supports some of the world's biggest mines (gold, silver, copper, and more). This image looks down the bull's-eye of Peru's Toquepala copper mine, a steep sided and stepped open-pit mine. At the surface the open pit is 6.5 km across and it descends more than 3000 m into the earth. Astronaut photograph was acquired on September 22 2003 from the International Space Station (ISS) / Bridgeman Images
