The Kamchatka Peninsula is basically a 1,250km peninsula in the Russian Far East, with an area of about 270,000 km2 (100,000 sq mi). According to TwistedSifter, the stunning ice cave you see above “was formed by a stream flowing from the hot springs associated with the Mutnovsky Volcano – the roof of this cave is now so thin that sunlight penetrates through it, eerily illuminating the icy structures within.” Continue reading for a video, more pictures, and additional information.

Although Kamchatka lies at similar latitudes to Great Britain, cold arctic winds from Siberia combined with the cold Oyashio sea current result in the peninsula being covered in snow from October to late May. Under the Koppen climate classification Kamchatka generally has a subarctic climate (Dfc) but higher and more northerly areas have a polar climate (ET). Kamchatka is much wetter and milder than eastern Siberia, and is essentially transitional from the hypercontinental climate of Siberia and Manchuria to the rain-drenched subpolar oceanic climate of the Aleutian Islands.
