Laguna Amarga es una laguna mesosalina, endorreica, somera (profundidad máxima 4 m) con un área actual de 3,18 km2. En las laderas de la cuenca se observan 7 paleolineas de costa que evidencian fluctuaciones del nivel lacustre. Laguna Amarga es el hábitat de extensas colonias vivas de estromatolitos, análogos de los antiguos fósiles que se encuentran en numerosas rocas a partir del Arqueano. Los estromatolitos nos permiten estudiar y contemplar verdaderos fósiles vivientes, aumentando el conocimiento de los orígenes de la vida en la Tierra. Los estromatolitos son depósitos órgano sedimentarios laminares que resultan de la acreción de comunidades microbianas bénticas que atrapan sedimentos y/o forman focos para la precipitación mineral. Los biominerales que se forman en los estromatolitos de Laguna Amarga involucran diferentes tipos de carbonatos Aragonito, Dolomita y Naprolita. La proliferación de dichos organismos en condiciones extremas permite inferir que ellos son los primeros postulantes de ser encontrados en ambientes extraplanetarios como la agresiva atmosfera de Io o las antiguas paleo cuencas de Marte que posiblemente estuvieron rellenas con aguas ricas en carbonatos.

Esta es una vista general de South America

South America makes up the southern half of the Americas and a large part of Latin America. It's home to the world's longest mountain range, biggest waterfall and largest river -- even these mammoths pale in comparison to the stunning variety of life forms thriving in the rainforest.

To the northwest, off the coast of Ecuador, lie the Galapagos Islands, which are unique for hosting species not found anywhere else on earth. These were the subject of study for Charles Darwin in his theory of evolution, which he himself said will require proof in every single case.

The main languages in South America are Spanish and Portugese, which basically tells you which European countries colonized the place. The South American wars of independence took place over two decades in the early 19th century, led by Simon Bolivar of Venezuela and Jose san Martin of Argentina.

Following liberation from Portugal and Spain, South America took off into its own development, capitalizing on the rich deposits of oil, gold, copper, silver and tango musicians.

Brazil is the largest country in South America and home to one of the world's best parties, Carnaval. Have you heard of samba music? How about bossa nova? Maybe dancing for three days straight?

I can't say enough good things about South America. All the world's continents have amazing secrets and treasures laying in wait for your discovery, but in South America... just have a look at our pictures while you're waiting for online confirmation of your plane tickets to hit your inbox.
