The future is likely less skiable, thanks to climate change

Annual snow cover days in all major skiing regions are projected to decrease dramatically as a result of climate change, with one in eight ski areas losing all natural snow cover this century under high emission scenarios. ...

New research challenges hunter-gatherer narrative

The oft-used description of early humans as "hunter-gatherers" should be changed to "gatherer-hunters," at least in the Andes of South America, according to groundbreaking research led by a University of Wyoming archaeologist.

The Andes is the world's longest continental mountain range. It is a continual range of highlands along the western coast of South America. This range is about 7,000 km (4,300 mi) long, about 200 km (120 mi) to 700 km (430 mi) wide (widest between 18 degrees South and 20 degrees South latitude), and of an average height of about 4,000 m (13,000 ft).

Along its length, the Andes is split into several ranges, which are separated by intermediate depressions. The Andes is the location of several high plateaux – some of which host major cities such as Quito, Bogotá, Arequipa, Medellín, Sucre, and La Paz.

The so-called Altiplano plateau is the world's second-highest plateau following the Tibetan plateau. The Andes extend from north to south through seven South American countries; Argentina, Bolivia, Chile, Colombia, Ecuador, Peru and Venezuela.

The Andes range is the world's highest mountain range outside of the continent of Asia. The highest peak, Mt. Aconcagua, rises to an elevation of about 6,962 m (22,841 ft) above sea level. The peak of Chimborazo in the Ecuadorean Andes is farther from the centre of the Earth than any other location on the Earth's surface. This is because of the equatorial bulge that results from the Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina frontier which rises to 6,893 m (22,615 ft), and over 50 other volcanoes that rise above 6,000 m.
