The largest lake in Kyrgyzstan and Central Asia — Issyk-Kul. The total volume of water of the Issyk-Kul lake — 1738 km2, its average depth-278 m, maximum depth-668 m, the coastline stretches for 688 km, the length of the largest lake of Kyrgyzstan from the North to the South — 58 km, and from West to East is 182 km away.
Lake Issyk-Kul located at an altitude of 1609 m above sea level between the ridges of the Northern Tien-Shan: Terskey Ala-too and Kungei Ala-too. Issyk-Kul is one of the largest mountain lakes in the world.
The largest lake of Kyrgyzstan is powered by water more than eighty rivers, but none of them carries its water back, so the water in the lake is salty (salinity — 5,90%). The ancient name of the lake — “ACE-Kul” — «Salty lake” speaks for itself, the water here is not potable. The present name of the lake — “Issyk-Kul lake” is translated from Kyrgyz as the “Hot lake”. It is also logical — the lake never freezes (even in the depths of winter and severe frosts), due to the considerable depth of the water does not become completely cool. In July and August, the water warms up to +18−20°, and in winter cools to + 4,2−5,0°.

American Arizona attracts tourists primarily for its red rocks, mysterious mirages and, of course, located here is the Grand canyon. But the wonders of nature in Arizona is not limited to, some of them even created as a direct result of human activity. For example, lake Powell is rightly considered the most beautiful artificial lake in the world.
Lake Powell, located on the border of Utah and Arizona, was created by the construction of a dam on the Colorado river in the Glen Canyon area. Although the construction of the dam and was met by numerous protests from ecologists and anthropologists, the project was completed on time, namely in 1963.
The shoreline of the lake is 3156 km and by this indicator it is not only a leader in the U.S. among the lakes, but this figure even more than the total length of the American coast of the Pacific ocean!
The maximum width of lake Powell reaches 40 km and depth of about 170 meters. It is of interest that the hydroelectric power station built on the dam, fully supplies electricity to five States of the USA.
Water not only fills Glen Canyon, and about 90 smaller canyons adjacent to it. The best Continue reading
11km NNW of West Yellowstone, Montana
Yellowstone is one of the largest known volcanoes in the world and the largest volcanic system in North America. The volcano is found above an intra plate hot spot that feeding the magma chamber underneath Yellowstone for at least 2 million years.
The giant Caldera is the product of a major collapse of the crust after 3 so-called ultra-plinian or Super-volcano volcanoes – large explosive events that occur several hundred to several thousand cubic km of magma. These eruptions happened 2.1, 1.3 and 0.64 million years ago.
Yellowstone is also the world’s largest hydrothermal system. It contains 182 Geysers, mud pools and fumaroles. The most famous feature in Yellowstone is old faithful geyser.
Future Super-volcano eruptions at Yellowstone?
Yellowstone Magma Chamber is considered to be still active and contain at least 15,000 cubic km of melt.
It can not be excluded and predicted that there will be another Super-volcano eruption at Yellowstone in the future (geological).
In recent years, the Caldera has been studied and monitored more closely. In recent years, Yellowstone demonstrates unrest in the form Continue reading
