Squeezed between the Black and Caspian Seas, the Caucasus chain is nearly 1500 km long and about 130km wide. The height of the Caucasus accounts for the range's considerable snow-cover and although there are many glaciers - crevasses can be a problem (particularly on Elbrus) they are generally smaller than those found in the Alps.
Elbrus is a massive two-headed extinct volcano, plastered in ice. Approximately 70 glaciers, large and small, cover the Elbrus massif with 145 sq km of ice, in places hundreds of metres thick.
