9Denali in Alaska
Source: Link
This 20,320-foot mountain is prone to earthquakes and has the combination of extreme latitude and high altitude that can cause altitude sickness to kick in much quicker. Compared to those at the equator, a peak this size has approximately half as much oxygen at its summit than at sea level, due to its latitude. Due to the large width of Mount Denali above sea level, compared to other mountains, its climbing is more difficult. This is because the climber has to travel more hours at a high altitude with less oxygen, which will cause the fastest hit from the altitude sickness. Denali, the highest mountain in North America, located in the Alaska Range, above the seismically active tectonic plate of the Pacific, was created by powerful earthquakes in Alaska 60 million years ago. There has been a lot of discussion about the name of the remarkable mountain with its two ridges, until finally in 2015 it was officially named Denali. This mountain, the ridge part of Denali National Park, has for years attracted the attention of people and various expeditions in search of gold, or attempts to reach the top of the mountain. The first ascent of Denali’s main peak was made in 1913, which was followed by other group climbs. The mountain is a granite rock, where the upper part is a snow-covered desert, which supplies five large glaciers of great ecological importance to our planet. Denali attracts thousands of visitors with its wonderful landscapes and rich variety of wildlife. Click the next ARROW to see the next image!
