Aconcagua | Mendoza

Aconcagua is the highest mountain in both the Western Hemisphere and Southern Hemisphere, standing at 6,960 meters (22,837 feet) above sea level. It is located in the Andes Mountains, on the border between Argentina and Chile, in the Aconcagua Provincial Park, near the town of Mendoza, Argentina.

Geographical and Climatic Characteristics

Location

• Aconcagua is located in the Andes Mountain range, approximately 120 km northwest of Mendoza city, Argentina.
• The mountain's summit is positioned near the Argentine-Chilean border, making it an important geographical landmark in South America.
• The mountain is part of the Aconcagua Provincial Park, which is a protected area that includes diverse landscapes such as high-altitude plateaus, glaciers, rivers, and rocky terrains.

Climate

• Aconcagua is known for its extreme climate due to its high altitude and location near the equator.
• Summers (December–February) are warmer but still cold at the summit, with temperatures ranging from 10°C (50°F) to 15°C (59°F).
• Winters (June–August) are harsh and extremely cold, with temperatures dropping to -20°C (-4°F) or lower, especially at the higher altitudes.
• The region experiences strong winds, particularly at higher elevations, and heavy snowfall can occur during the winter months.

Climbing Aconcagua

Routes

Aconcagua is a popular destination for mountaineers, offering several climbing routes. The two most popular routes are:

Normal Route

• The Normal Route is the easiest and most accessible route, making it the most commonly used for summit attempts.
• It is a non-technical climb, meaning it doesn’t require advanced mountaineering skills like ice climbing or rock climbing, but it still presents significant challenges due to the altitude and weather conditions.
• Duration: The climb typically takes about 16-20 days, allowing time for acclimatization.
• The route involves several camps at varying altitudes (Plaza de Mulas Base Camp, Camp 1, Camp 2, and the summit).
• The final summit push from Camp 3 (at around 6,000 meters) is challenging due to altitude sickness risks.

Polish Glacier Route

• The Polish Glacier Route is considered more challenging and is suited for experienced climbers.
• It involves glacier climbing, technical equipment such as ice axes and crampons, and steep ascents through difficult terrain.
• This route is favored by advanced mountaineers seeking more technical challenges.

Challenges and Risks

• Altitude: Aconcagua’s high elevation leads to altitude sickness (also known as acute mountain sickness, AMS), which can cause symptoms like headaches, nausea, dizziness, and shortness of breath. Proper acclimatization is crucial.
• Weather: The mountain’s weather is unpredictable and extreme. High winds, freezing temperatures, and snowstorms can strike suddenly, making the ascent risky, particularly in winter.
• Technical Difficulty: Though the Normal Route does not require technical climbing skills, it still presents challenges, especially in high-altitude conditions, rocky terrain, and the altitude-related physical strain.

Climbing Season

• The best time to climb Aconcagua is during the summer months, from November to March, when conditions are generally more favorable.
• The peak climbing season is from December to February, with many climbers attempting the summit during this period.
• Outside of this season, the weather conditions are extremely harsh, and access to the mountain becomes very limited.

Aconcagua Provincial Park

• Aconcagua is located within the Aconcagua Provincial Park, a protected area that is home to several unique ecosystems, wildlife, and remarkable landscapes.
• The park encompasses lowland deserts, forests, high-altitude plateaus, and glaciers.
• Wildlife: Some species that can be found in the park include guanacos (a relative of llamas), Andean condors, pumas, and foxes.

Getting to Aconcagua

Entry Fees and Regulations

• To climb Aconcagua, visitors must pay a climbing permit fee, which is required to enter the park and access the climbing routes.
• The permit fee is typically higher for foreign climbers, and it includes access to base camps and some services.
• It is essential to register with park authorities before starting the climb.
