What makes the Mountains Deadly to Climb? Top 8 dangerous mountains in the world.

The beautiful mountains are the real challenge to accomplish. It requires courage to accomplish the climb. There are many factors responsible to make the mountains challenging and fatal. The high ratio of the ascent to the death makes the mountain more deadly which is dependent on some of the factors listed as follows:

Altitude Sickness

Altitude Sickness is a great threat in the high Himalayas. As the altitude increases, the atmospheric pressure decreases which make the climbers uncomfortable. This can affect different aspects of the health of the climbers. The less concentration of the oxygen in the environment will make the climbers difficult to take breathe.

The altitude above 8,000 meters is called Death Zone. Above 8,000 meters the atmospheric conditions are beyond the adaptive capacity of the climbers. Their body suffers from different abnormalities such as dizziness, nausea, headache, and shortness of breath. Inabilities to adapt in such an adverse condition are the cause of many deaths in the mountains.


The weather in the mountains is never stable. The extreme cold and the wind sometimes do not allow the climbers to move forward. The atmospheric temperature drops by 0.65°C per 100 meters of height gained. Thus, as climbers reach 8,000 meters the temperature will be 57°C less than that at sea level. The exposure to extreme cold temperature can lead to frostbite and also deaths.


Falls is a major life risk in the mountains. The risk of the fall exists in all steps: during the climb, on high ridges, and even after the summit.


Avalanches are obviously the big name in the list. When the massive mass of the ice slides down from the top, the climbers get no time to run away from the disaster. Even simple natural triggers can initiate the avalanche. For example; the fresh snow setting on the old snow. When the avalanche starts, it gains a really high speed that if the climber gets caught, he/she is buried alive or moved down to thousands of feet.


A crevasse can be deep and wide enough to invite death. A crevasse is found near the new snow bridge which is made up of snow in a recent previous year. A crevasse may not be distinguished from the surface but once a climber drops down to the bottom of the crevasse, there is almost zero chance to come out.

Thus, next time when you are going for an adventure to climb the mountain, study the fatality rate of the mountain so that you can have a general idea of the level of danger you will be facing. Make sure you make a proper study of the climate during your time of visit and most important partner up with someone who takes your health as a priority element.
