Climbing the north face of Mount Everest reveals a world of high-altitude danger and historic achievement. This iconic route—on the Tibetan side—draws fewer climbers but demands more skill. Let’s explore its terrain, key features, and what makes it uniquely dramatic.

What Is the North Face of Mount Everest?

The north face of Mount Everest is the mountain’s northern side, accessible via Tibet. This remote region is known for steep couloirs, icy ridges, and harsh conditions. It’s a place where “a simple slip would mean death.” 

Geography & Key Route Features

Climbers embark from Rongbuk Base Camp (~5,150 m). The route advances via the North Col—a glacial ridge connecting Everest and Changtse—and follows the Northeast Ridge.

Along the way are the infamous Three Steps—rock pinnacles near the summit at ~8,560 m, 8,610 m, and 8,710 m. The Second Step is nearly vertical and requires a ladder.

Two steep gullies—the Hornbein Couloir and Norton Couloir—flank the face. Hornbein, with inclines ranging from 47° to 60°, is especially treacherous.

History: Mysteries and First Ascents

In 1921, Mallory, Wheeler, and Bullock first reached the North Col. Mallory later returned with Sandy Irvine in 1924, vanishing near the summit. Mallory’s body was found in 1999.

The first confirmed summit via the northeast ridge from Tibet occurred on May 25, 1960, when Chinese climbers Wang Fuzhou, Qu Yinhua, and Gongbu reached the top.

The Hornbein Couloir was first climbed in 1963 by Tom Hornbein and Willi Unsoeld, who ascended the West Ridge before traversing to the north side.

Everest North Col: Access & Logistics

The Everest North Col is a high pass at ~7,000 m connecting Everest and Changtse. It was first reached in 1921 and serves as a staging area for climbers from Tibet.

Rongbuk Base Camp is accessed by road via Tingri and the Friendship Highway. A paved road built in 2015 made access far easier compared to Nepal’s approach. 

Why Climb the North Face?

Advantages:

• Avoids the dangerous Khumbu Icefall of the south route.
  
• Fewer crowds and less congestion.
  
• Lower permit fees, though overall logistics can cost more.
  

Drawbacks:

• Harsh weather: fierce winds and extreme cold. Summit winds often exceed 100 km/h; temps near –30°C, with wind chills around –50°C.
  
• Technical terrain: the steep couloirs, three Steps, seracs, and icy slopes demand high skills.
  
• Longer summit day (16–20 hrs) and lower rescue support.
  
• Slightly lower success rate (~55% vs. ~65% on south route).
  

Climbing Challenges at a Glance

Comparing North vs. South Routes

The south (Nepal) route is more popular and structured. It has better support, helicopter evacuation, and more trekking amenities.

But it also includes hazards like the Khumbu Icefall and traffic jams near the Hillary Step. Overcrowding has even led to dangerous delays.

The north route offers solitude and fewer icefall dangers—but trades them for technical difficulty and exposure to climate extremities.

Conclusion

The north face of Mount Everest defines high‑altitude ambition. Its rugged landscapes, technical hazards, and chilling beauty make it both alluring and fearsome. From Mallory’s mysterious disappearance to modern expeditions via the Hornbein Couloir—this route encapsulates the harshest side of Everest.

For skilled climbers seeking a serious challenge beyond crowds and conventions, the north face remains the ultimate test.

On May 28, 2025, Delta Air Lines Flight DL275, en route from Detroit Metropolitan Airport (DTW) to Tokyo Haneda Airport (HND), was unexpectedly diverted to Los Angeles International Airport (LAX) due to a technical issue. This article delves into the reasons behind the diversion, the airline’s response, and the implications for passengers and aviation safety.

Understanding the Cause of the Diversion

Approximately five hours into the flight, while cruising at 38,000 feet over the North Pacific Ocean, the flight crew received alerts indicating a malfunction in the Rolls-Royce Trent XWB engine’s anti-ice system. This system is crucial for preventing ice buildup on engine components during high-altitude flights in freezing conditions.

Technical Details of the Anti-Ice System Failure

The anti-ice system operates by directing hot bleed air from the engine’s compressors to critical components, maintaining temperatures between 400 to 600°F to prevent ice formation. In this instance, sensor data revealed:

• A 50% reduction in airflow
  
• A 25% decrease in bleed air pressure
  
• A 300% slowdown in valve response time
  
• A 30% drop in temperature below normal operating levels
  

These anomalies signaled a significant malfunction, prompting the crew to initiate a diversion to the nearest suitable airport equipped to handle such emergencies.

Decision to Divert to Los Angeles

The choice of LAX was strategic, considering several factors:

• Proximity and Facilities: LAX is a major Delta hub with extensive maintenance facilities capable of servicing the Airbus A350-900.
  
• Safety Protocols: Landing at the nearest airport with appropriate facilities is standard procedure in aviation to ensure passenger safety.
  
• Weather Conditions: LAX offered favorable weather conditions for a safe landing, unlike other potential diversion airports.
  

At approximately 1:08 AM local time, the aircraft landed safely at LAX after more than 12 hours in the air. All 287 passengers and crew members were unharmed.

Passenger Experience and Airline Response

Upon landing, Delta’s ground crew promptly assisted passengers:

• Rebooking: Passengers were rebooked on alternative flights to their final destinations.
  
• Accommodations: Hotel rooms and meal vouchers were provided for those requiring overnight stays.
  
• Communication: Delta maintained clear communication, keeping passengers informed throughout the process.
  

While the diversion caused delays and inconveniences, passengers generally appreciated the airline’s swift and organized response.

Financial and Operational Impact

The diversion incurred significant costs for Delta Air Lines:

• Fuel and Landing Fees: Approximately $500,000
  
• Maintenance and Inspection: Around $300,000
  
• Passenger Services: Approximately $800,000 for accommodations, meals, and rebooking
  
• Lost Revenue: Estimated at $2.3 million due to the canceled Tokyo leg and cargo losses
  

In total, the incident cost Delta nearly $2.8 million.

Aviation Safety and Technological Considerations

This incident underscores the importance of advanced monitoring systems in aviation. Predictive maintenance technologies, utilizing AI and machine learning, could potentially detect early signs of system failures, allowing for proactive measures before departure. Implementing such technologies could enhance safety and reduce the likelihood of in-flight emergencies.

Conclusion

The diversion of Delta Flight DL275 to LAX highlights the airline’s commitment to passenger safety and the effectiveness of established emergency protocols. While the incident resulted in financial costs and passenger inconveniences, the priority given to safety ensured a positive outcome. It also serves as a reminder of the critical role of technology and preparedness in modern aviation.
