Grand Prismatic Spring
USA

Nos encontramos en el Midway Geyser Basin junto al mayor manantial de las aguas termales de Yellowstone y de los Estados Unidos, con un diametro de unos 90 metros.

Su nombre proviene de la expedición Hayden de 1871, sus aguas se encuentra a una temperatura media de unos 70º y el vapor en su superficie refleja sus brillantes colores. Estos colores empiezan desde un azul profundo en el centro, verde, unas bandas de amarillo, naranja, y rojo en su borde externo.

En el centro del manantial el agua a 87º es demasiado caliente para que exista vida en ella. Los colores amarillo, naranja y rojo son producidos por los pigmentos de una bacteria que habita en los bordes. Los cientificos de la NASA estudian los manantiales de aguas termales de Yellowstone porque pueden ser similares a los entornos donde la vida evolucionó en la Tierra. Otros cuerpos del sistema solar, como Europa o Marte, podrían tener manantiales de aguas termales también, posiblemente con vida.

Puedes ver otra vista panoramica de Yellowstone, en este caso de los manantiales del West Thumb Geyser basin junto al lago Yellowstone.

More About USA

The United States is one of the most diverse countries on earth, jam packed full of amazing sights from St. Patrick's cathedral in New York to Mount Hollywood California.The Northeast region is where it all started. Thirteen British colonies fought the American Revolution from here and won their independence in the first successful colonial rebellion in history. Take a look at these rolling hills carpeted with foliage along the Hudson river here, north of New York City.The American south is known for its polite people and slow pace of life. Probably they move slowly because it's so hot. Southerners tend not to trust people from "up north" because they talk too fast. Here's a cemetery in Georgia where you can find graves of soldiers from the Civil War.The West Coast is sort of like another country that exists to make the east coast jealous. California is full of nothing but grizzly old miners digging for gold, a few gangster rappers, and then actors. That is to say, the West Coast functions as the imagination of the US, like a weird little brother who teases everybody then gets famous for making freaky art.The central part of the country is flat farmland all the way over to the Rocky Mountains. Up in the northwest corner you can find creative people in places like Portland and Seattle, along with awesome snowboarding and good beer. Text by Steve Smith.
