Mount Elbrus is the highest mountain in Russia and in Europe, and the tenth most prominent peak in the world. A dormant volcano, Elbrus is in the Caucasus Mountains in Southern Russia, near the border with Georgia.

Elbrus has two summits, both of which are dormant volcanic domes. The taller west summit is 5,642 metres (18,510 ft);, the east summit is 5,621 metres (18,442 ft). The east summit was first ascended on 10 July 1829 (Julian calendar) by Khillar Khachirov. His nationality is claimed both by Kabardians and Karachay and used by nationalists of both sides. He was a guide for a Imperial Russian army scientific expedition led by General Emmanuel, and the west summit (by about 20 m; 66 ft) in 1874 by a British expedition led by F. Crauford Grove and including Frederick Gardner, Horace Walker, and the Swiss guide Peter Knubel of St. Niklaus.

The Caspian Sea is the largest enclosed inland body of water on Earth by area, variously classed as the world's largest lake or a full-fledged sea. It is in an endorheic basin (a basin without outflows) located between Europe and Asia. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the west, Iran to the south, and Turkmenistan to the southeast.

The Caspian Sea presently lies about 28 m (92 ft) below sea level in the Caspian Depression, to the east of the Caucasus Mountains and to the west of the vast steppe of Central Asia. The sea bed in the southern part reaches as low as 1023 m below sea level, which is the second lowest natural depression on earth after Lake Baikal (-1180 m). The ancient inhabitants of its coast perceived the Caspian Sea as an ocean, probably because of its saltiness and large size.

The sea has a surface area of 371,000 km2 (143,200 sq mi) (not including the detached lagoon of Garabogazkol) and a volume of 78,200 km3 (18,800 cu mi).[5] It has a salinity of approximately 1.2% (12 g/l),[6] about a third of the salinity of most seawater.
