Algeria - September 29th, 2009

This image of western Algeria is divided in half by a long, curving mountain range. These mountains, running from north to south through the center, reach heights of over 1400 meters to the north and gradually decrease to 800 meters to the south.

To the east of the mountains lies an expanse of sand dunes, some of which reach heights of 600 meters.

To the west lies an artificial reservoir by the town of Djorf Torba. East of the reservoir is the city of Béchar, the capital of Béchar Province, appearing here as a grey area at the foot of the mountains.

West of the Andes Mountains, two large bays south of the port city of Puerto Montt and Reloncaví Sound separate Chiloé Island from the Chilean mainland. These are the Gulf of Ancud (above) and the Gulf of Corcovado (below), a foreland basin that has been carved out by Quaternary glaciers.

Chiloé Island (Spanish: Isla de Chiloé), also known as Greater Island of Chiloé (Isla Grande de Chiloé), is the largest island of Chiloé Archipelago off the coast of Chile, in the Pacific Ocean. The island is located in southern Chile, in the Los Lagos Region.

Chiloé Island (8,394 km², 3241 sq mi), is the second largest island in Chile (and the fifth largest in South America).  The island is 190 km (118 mi) from north to south, and averages 55–65 km wide (35 to 40 mi).

Another important body of water visible in this fine image of Patagonia is General Carrera Lake (known as Buenos Aires Lake in Argentina) on the Chile-Argentina border, bottom center.

The Oslofjord is a bay in the southeast of Norway, stretching from an imaginary line between the Torbjørnskjær and Færder lighthouses and down to Langesund in the south to the city of Oslo in the north.

In spite of its name, it is not, geologically speaking, a fjord, but rather a bay. The bay is divided into the inner (indre) and outer (ytre) Oslofjord at the point of the 17 km long and narrow Drøbaksundet.

The entire population situated around the Oslofjord including Oslo is about 1.7 million, and the total population of all the counties situated around the fjord is approximately 2 million.

The rugged Tian Shan Mountains surround the endorheic lake Issyk Kul in eastern Kyrgyzstan. They are one of the longest mountain ranges in Central Asia, stretching some 2,800 kilometres (1,700 mi) eastward from Tashkent in Uzbekistan.

In this orthorectified image, the Teskey Ala-Too Range dominates the lake’s southern shore, whie the Kyungey Ala-Too Range runs parallel to the north shore.

The peaks of these ranges are usually snow-capped; however, Issyk Kul never freezes, hence its name, which means “warm lake” in the Kyrgyz language.
