Grand Geyser, Yellowstone. Travel to the country of geysers Yellowstone

Yellowstone National Park is famous all over the planet, and especially he is famous for geysers. In general, there are not so many geysers on Earth. The most famous of them are in Iceland, New Zealand and the USA. Warmed in the depths of the Earth, magma flows approach its surface and come into contact with the groundwater, turning it into steam, whose pressure rises until it exceeds the pressure of the water column above it. Then hot streams of water mixed with steam spill out and out. A lively fountain of boiling water usually erupts suddenly and unexpectedly.

About half of all geysers in the world are located in Yellowstone National Park, and most of them are concentrated in the Upper Geyser Basin, of which Geyser Hill is also a part. "Hydrothermal Field of Wonders" is the name of the region with the five largest geysers: Grand Geyser, Old Faithful, Castle, Daisy, and Riverside.

About 140,000 tourists visit Yellowstone in the winter season from mid-December to early March. Compared to the three million people visiting the park throughout the year, with the onset of winter, the vast territory of the park looks surprisingly deserted. But the wildlife of the park is much easier to see at this time of the year, and the soaring hot springs surrounded by a cover of snow and ice look especially beautiful.

In the history of the Earth, periods of warming have always alternated with periods of cooling. In addition to astronomical factors, the global oceanic "conveyor belt" of currents also affects the planet's climate, which depends on the location of high mountains and the continents themselves. One of the most important factors of climate variations is a change in the intensity and nature of volcanism with a frequency of up to tens of thousands of years, as a result of which a huge amount of greenhouse gases can enter the atmosphere, far exceeding modern anthropogenic emissions.

Journey to Yellowstone National Park (Wyoming, USA). Here you are waiting for breathable geysers, multimeter waterfalls, amazing canyons and untouched human wildlife, along with all its inhabitants: bears, deer and bison. The number of "hot spots" in the park is estimated at about 10 thousand. As part of a scientific study that ended in 2011, it was found that 1283 geysers erupted in Yellowstone, 465 of which are active during the average year.

Yellowstone, like the Hawaiian Islands, is located in the upper part of the area called the "hot spot", in which the giant flows of molten magma are much closer to the surface of the planet than usual. In Yellowstone, there are thousands of small Earthquakes per year, but almost all of them are not noticeable to humans. Due to the location in the center of the ancient caldera, from 200 to 250 geysers erupt upward steam and boiling water each year, which made Yellowstone the place of the highest concentration of active geysers in the world.

Thermal springs constantly change the temperature and nature of behavior, some fade out, and new ones appear, suddenly spewing out puffs of steam, quite capable of killing a huge bison on the spot. Ex-thermal tourism: incredible geysers from around the world, demonstrating the power of the Earth. There are not so many places on the planet where you can personally observe this unique natural phenomenon.

As an independent industry, the US tourism originated in the 1850s. The period of its most active development came in the 50s of the twentieth century. This happened due to the emergence of regular flights between the continents. Nowadays, up to 50 million tourists visit the country annually. US tourism is becoming more popular every year.

Today, most discussions of climate change in the media boil down to the need to reduce the anthropogenic emissions of carbon dioxide into the atmosphere in order to reduce the greenhouse effect that leads to climate warming. And, according to a number of foreign experts, the current total anthropogenic CO2 emissions are approximately an order of magnitude higher than volcanic.

This question certainly deserves a detailed study. But here's what's interesting: as the results of research on the ice of Antarctica and Greenland show, in which ancient air "bubbles" were preserved, the concentration of CO2 in the atmosphere changed after temperature changes, that is, the climate first changed, and only then did the carbon dioxide content in the air. So there is a possibility that we are now confusing cause and effect. The notorious problem of the destruction of the ozone layer due to the release of freons and other similar compounds should also be attributed to the same series.
