The mountain range running diagonally through the right side of this orthorectified image can be divided into two parts: the Olaroz Grande (above) and Olaroz Chico (below). The range is located in the Susques Department of Argentina’s Jujuy Province, just east of the Chilean border.

Olaroz Grande reaches heights of over 4800 meters, while the aptly named Olaroz Chico is lower at between 4200 and 4400 meters. Located near the mountains is the similarly named Salar de Olaroz, a salt flat.

The Caucasus Mountains is a mountain system in Eurasia between the Black Sea and the Caspian Sea in the Caucasus region. It is made up of two separate mountain systems: the Greater Caucasus Mountain Range and the Lesser Caucasus Mountains, which run parallel to the greater range at a distance averaging about 100 km (60 mi) south.

In this orthorectified image, some of the slopes of the Greater Caucasus Mountain Range in southern Russia, just north of the border with Georgia, can be seen. The Russian terrain here is part of the Kabardino-Balkar Republic, west, and the Republic of North Ossetia-Alania, east.

Located in the Kabardino-Balkar Republic is the highest peak in the Caucasus ranges: Mount Elbrus. This volcanic mountain rises to a height of 18,506 feet (5,642 meters) above sea level. The highest peak in the Republic of North Ossetia-Alania, on the other hand, is Mount Dzhimara at 4,780 m.

The Yukon River meanders across this orthorectified image of Denali Borough in Alaska, USA, towards Canada’s Yukon Territory, to which it lends its name. Over half of the 3,700 km (2,300 mi) long river lies in the state of Alaska, making it the longest in the state. Many lakes can be seen scattered around the river.

North of the river are the foothills of the Brooks Range, a mountain range that stretches from west to east across northern Alaska and into Canada’s Yukon Territory, a total distance of about 1100 km (700 mi). The mountains top out at over 2,700 m (9,000 ft).

Argentina and Chile - September 29th, 2009

Many volcanoes can be seen along the border of Chile (left) and Argentina (right) in the upper left quadrant of this orthorectified image. Of particular note are the volcano Ojos del Salado and the mountain Cerro el Muerto, near Laguna Verde, the greyish-looking body of water in that same quadrant.

Laguna Verde is a salt lake in the Andes Mountains of Chile. It lies in the Atacama Region, near San Francisco Pass, surrounded by high mountains. The volcano Ojos del Salado marks the south border of its basin.

Visible directly south of the lake is Cerro el Muerto (sometimes translated as “Death Mountain” or “The Dead One”), a mountain peak that is part of the Andes mountain range. It is also known as the 16th of the largest mountain peaks in the Argentine-Chilean border at 6488 m.

The closest neighboring mountain is Ojos del Salado, visible to the southwest on the edge of the image, a massive stratovolcano in the Andes on the Argentina-Chile border and the highest volcano in the world at 6891 m. It is also the second highest mountain in the Western Hemisphere and the highest in Chile. Its name comes from the enormous deposits of salt that, in the form of lagoons or “eyes”, appear in its glaciers

Due to its location near the Atacama desert, the mountain has very dry conditions with snow only remaining on the peak during winter. Despite the generally dry conditions, there is a permanent crater lake about 100 m in diameter at an elevation of 6390 m on the eastern side of Ojos del Salado. This is most likely the highest lake of any kind in the world.

Iran - September 24th, 2009

This orthorectified image shows part of the province of Kerman, in southeastern Iran. Many of the ridges visible here reach heights of about 1600 meters.

The ridges of Kerman province are the continuation of Iran’s central mountain ranges, which extend from Azarbaijan, branch out across the country’s central plateau, and terminate in Baluchestan.

Several small towns can also be seen at the foot of the mountains in the lower left corner. The largest of these is Zarand, with a population of about 30,000 people.
