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

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
