Why is siula grande such an exterme environment?

Siula Grande, located in the Peruvian Andes, is considered an extreme environment due to its harsh weather conditions, high altitude, and challenging topography. At elevations exceeding 6,000 meters (19,685 feet), the air is thin, leading to reduced oxygen levels, which can cause altitude sickness for climbers. Additionally, the region experiences extreme temperature fluctuations and unpredictable weather, including heavy snowfall and storms, making it perilous for exploration and climbing. The combination of these factors creates a setting that tests the limits of human endurance and survival.
