Yala Glacier: First Dead Glacier in the Hindu Kush Himalaya

Most Himalayan glaciers are famous for their size, beauty, or their place on popular trekking routes, but Yala Glacier is different. In May 2025, it became the first glacier in Asia to be officially declared “dead” after decades of rapid ice loss.

This announcement marked a turning point in glacier research and brought attention to the impact of climate change on the Himalayas. Even though Yala Glacier’s “dead” status has attracted worldwide attention, it remains an important place to visit in Nepal’s Langtang region.

Trekkers come for the mountain views, climbers use it to reach Yala Peak (5,732 m/18806 feet), and scientists keep studying its changing landscape. All of this makes Yala Glacier one of the most significant glaciers in the Hindu Kush Himalaya (which comprises the Hindu Kush, Karakoram, and Himalayas).

This guide covers what you need to know about Yala Glacier, including its location, features, how it formed, its scientific relevance, how to reach it, and its significance in the entire region.

It also explains why it was declared “dead” and what that means for the future of glaciers in the Himalayas.

Yala Glacier Overview

Before exploring this Glacier in detail, here’s a quick summary of its key geographic, scientific, and trekking-related facts.

Where is Yala Glacier Located?

Yala Glacier sits in the upper Langtang Valley of Rasuwa District, Nepal, within Langtang National Park. Its approximate coordinates are 28.236°N and 85.617°E. It lies close to the Nepal-Tibet (China) border in the central Himalayas, forming part of the Hindu Kush Himalayan (HKH) region. 

The glacier sits above Kyanjin Gompa, the last major settlement on the Langtang Valley Trek, making it one of Nepal’s most accessible glaciers.

Although it is only about 28 km north of Kathmandu in a straight line, reaching the glacier usually requires 6-10 days of trekking, depending on the route and itinerary.

This Glacier is closely associated with Yala Peak (5,732 m/ 18,806 ft), a popular trekking peak for beginners. The glacier lies just above Yala Base Camp, and most climbers pass by it on their way to the summit.

From the glacier and nearby ridges, visitors can enjoy panoramic views of Shishapangma (8,027 m/ 26,335 ft), the last 8,000-meter mountain located entirely in Tibet. Along with Langtang Lirung, Dorje Lakpa, Gangchempo, and other surrounding Himalayan peaks.

If you’re planning to climb Yala Peak, the 11-day Yala Peak Climbing itinerary organized by Himalayan Masters includes an overnight stay at Yala Base Camp. It offers trekkers a chance to visit Yala Glacier before making their summit push.

The glacier is only a short walk from the base camp and is one of the trek’s most memorable highlights.

The Geographic Setting of Yala Glacier

Yala Glacier sits in a high-altitude basin below Yala Peak, Langtang Lirung, Gangchempo, and Naya Kanga in the Langtang Himal.

The glacier is approximately 1.4 km long as of 2021 and ranges from about 5,170 to 5,750 meters (16,962 to 18,865 feet) in elevation; scientists classify it as a plateau glacier. The upper ice surface is cleaner than that of many other Himalayan glaciers, which often carry a thick layer of debris.

As the glacier melts, it feeds Langtang Khola, one of the main rivers in the Langtang Valley. The river later joins the Trishuli River, which flows into the Gandaki (Narayani) River before becoming part of the Ganges River Basin.

The glacier sits in an open alpine area above the tree line, and moraines, rocky slopes, and permanent snowfields surround it.

Because it is close to Kyanjin Gompa and popular trekking trails, it is one of the easiest glaciers to reach in Nepal for both visitors and researchers.

The Formation of Yala Glacier Began Thousands of Years Ago

Like most Himalayan glaciers, this ice mass formed over thousands of years as layers of snow accumulated at high elevations.

As fresh snowfall continued to build, the weight of the upper layers compressed the lower snow into dense glacial ice. Gravity then caused the ice mass to move slowly downhill, forming the glacier over time.

As long as new snowfall replenished the glacier, the accumulated ice slowly deformed and flowed downslope under its own weight. This gradual movement transported ice from the higher accumulation zone to the lower ablation zone, where melting occurred.

The continuous balance between snowfall and melting allowed Yala Glacier to remain active for thousands of years. However, as rising temperatures increased melting and reduced snow accumulation, the glacier’s movement slowed.

During its active years, the moving ice carved the surrounding landscape and left behind moraines made of rock, gravel, and sediment. These glacial deposits remain visible around the glacier today and provide evidence of its past movement.

Yala Glacier is smaller and less complex than many other glaciers such as Khumbu and Ngozumpa in Nepal. Still, it has helped shape the upper Langtang Valley and provides scientists with important information about how Himalayan glaciers react to climate change.

Yala Glacier River: Where the Meltwater Goes

Yala Glacier feeds the Langtang River, one of Nepal’s main rivers that flows through the Langtang Valley. During warmer months, melting snow and ice from the glacier contribute to the river’s flow, supplying freshwater to downstream ecosystems and communities.

From Langtang River, the water joins the Trishuli River, which later flows into the Gandaki (Narayani) River. The Gandaki eventually becomes part of the Ganga River Basin, one of South Asia’s largest river systems.

This river system supports farming, drinking water, and hydropower projects in central Nepal. Even though Yala Glacier is small, it adds to this larger watershed along with other glaciers and seasonal snowfields in the Langtang Himal.

But as the glacier keeps losing ice, scientists are monitoring carefully to see how these changes could affect water supplies and river flow in the future.

Geological history of Yala Glacier

Yala Glacier is part of the Langtang Himal, a mountain range that the collision of the Indian and Eurasian tectonic plates formed.

As the Himalayas rose over millions of years, the high elevation created the cold conditions needed for glaciers to form in the region.

During colder climatic periods, glaciers in the Langtang Himal expanded much farther than they do today. Yala Glacier occupied a larger area and gradually modified the surrounding mountain landscape through erosion and ice movement.

As the climate warmed, the glacier began to retreat, leaving behind moraines and other glacial deposits that mark its previous extent.

Since the 1970s, Yala Glacier has experienced a dramatic decline. Monitoring by the International Centre for Integrated Mountain Development (ICIMOD) shows the glacier has lost around two-thirds of its ice mass.

Its terminus is retreating by roughly 8–14 meters each year. The glacier surface is also thinning, losing about a meter of thickness annually.

These long-term changes led to Yala Glacier being symbolically declared a “dead glacier” in 2025. It now stands as one of the most significant examples of climate-driven glacier loss in the Hindu Kush Himalaya.

Yala Glacier Timeline

The history of Yala Glacier spans thousands of years, from its formation through natural snowfall to its recognition as the first glacier in Asia officially declared “dead.” The timeline below highlights the major milestones that have shaped the glacier and its role in climate research.

How to Get to Yala Glacier?

To reach Yala Glacier, you start with the Langtang Valley Trek, one of Nepal’s most popular routes. The trip begins with a drive from Kathmandu to Syabrubesi, the main entry point to Langtang National Park.

From there, the trail goes along the Langtang Khola through forests, Tamang villages, and alpine meadows before arriving at Kyanjin Gompa, the last permanent village in the valley.

Most trekkers visit Yala Glacier as a day hike from Kyanjin Gompa. The trail climbs gently above the village through open alpine areas before reaching the glacier’s moraine and viewpoints. The round trip usually takes 6 to 8 hours, depending on your pace, the route, and trail conditions.

Many climbers visit the glacier as part of their climb to Yala Peak, since the glacier is on the way to the trekking peak. You don’t need technical climbing skills to reach the glacier, but if you plan to climb this Peak, you should have the right equipment and an experienced guide.

Spring (March to May) and autumn (September to November) have the best weather, stable trails, and clear mountain views, so they are the most popular times to visit.

Can Himalayan Masters Help You Reach Yala Glacier?

Himalayan Masters can help you reach and experience Yala Glacier as part of its Yala Peak Climbing itinerary.

The glacier is encountered during the approach to Yala Peak, making the climbing trip a way to see the glacier while continuing toward the summit.

The itinerary includes the trek through the Langtang Valley to Kyanjin Gompa before continuing toward Yala Peak and its glacier-covered terrain.

If your main goal is to see Yala Glacier rather than climb Yala Peak, you can also visit the glacier area from Kyanjin Gompa as a day hike.

However, if you want to combine the glacier experience with a Yala Peak climbing expedition, Himalayan Masters provides the organized trekking and climbing itinerary, including the route, experienced guides, accommodation, and logistical support needed for the trip.

Trekking to Yala Glacier Is Suitable for Most Fit Trekkers

You don’t need technical climbing skills to reach Yala Glacier, so it’s one of the easiest glaciers to visit in Nepal. The route follows the well-known Langtang Valley Trek to Kyanjin Gompa, then continues to Yala Base Camp and the glacier. The path is clear, but you should be in good shape because of the high altitude and long days of walking.

Climbers consider Yala Peak a non-technical ‘Trekking Peak,’ so it’s a good option for those new to mountaineering. You only need to trek to visit the glacier, but if you want to climb Yala Peak, you’ll need some basic mountaineering gear and a guide.

Since the glacier is over 5,000 meters high, it’s important to spend at least one night in Kyanjin Gompa to help your body adjust and lower the risk of Acute Mountain Sickness (AMS). To avoid getting sick, drink plenty of water, take your time going up, and watch for early signs of altitude sickness to stay safe.

To visit Yala Glacier, you’ll need a Langtang National Park Entry Permit. It’s mandatory to hire a licensed guide for help with navigation, safety, and local knowledge, especially if you plan to go past the glacier toward Yala Peak.

The Majestic Mountains Surrounding Yala Glacier

Yala Glacier sits in a high mountain basin, surrounded by some of the most famous peaks in the Langtang Himal. These mountains create the cold, high-altitude setting where snow builds up and glacier ice forms.

The most prominent peak overlooking the glacier is Langtang Lirung (7,227 m / 23,711 ft), the highest mountain in the Langtang range. Other nearby peaks include Gangchempo (6,387 m / 20,955 ft), Naya Kanga (5,844 m / 19,173 ft), and Drapoche, all of which form part of the glacier’s surrounding landscape.

The glacier also lies close to Yala Peak, one of Nepal’s most popular trekking peaks. Because of its location, many trekkers pass near the glacier while climbing Yala Peak, enjoying panoramic sights of the surrounding mountains and, on clear days, Shishapangma (8,013 m / 26,289 ft) in Tibet.

All these peaks together create the dramatic alpine scenery that makes Yala Glacier a highlight of the Langtang Valley.

How Yala Glacier Shaped the Upper Langtang Valley

Although Yala Glacier is smaller than many glaciers in Nepal, it has contributed to the development of the upper Langtang Valley over thousands of years.

When the glacier was more extensive, its moving ice gradually eroded the underlying bedrock, widened parts of the valley, and transported rock fragments downslope.

As the glacier shrank, it left behind moraines made of boulders, gravel, and other sediments along its boundaries and lower slopes. Visitors can still see many of these features today, and they help scientists learn how the landscape has changed

Yala Glacier was only one of several glaciers that influenced the upper Langtang Valley. Together with neighboring glaciers such as Lirung glacier, it helped shape the alpine terrain that visitors see today, including broad glacial valleys, rocky ridges, and moraine-covered slopes around Kyanjin Gompa.

Why Was Yala Glacier Declared “Dead”?

Yala Glacier gained international attention in May 2025 after becoming the first glacier in Asia to be officially declared “dead.”

The announcement was made during Sagarmatha Sambad 2025, Nepal’s international climate dialogue, and coincided with the United Nations International Year of Glaciers’ Preservation 2025.

The declaration followed decades of scientific research showing the glacier has undergone rapid decline since the 1970s.

Studies found that this plateau glacier has lost around 66% of its ice mass, while its ice front has retreated significantly, and the remaining ice has become too thin to flow like a healthy glacier. Because it no longer functions as an active glacier, scientists classified it as “dead.”

On May 12, 2025, scientists, Buddhist monks, Indigenous community leaders, and local residents gathered in the Langtang Valley for a symbolic “ice funeral” to honor the glacier.

The ceremony included traditional Buddhist prayers and was organized by ICIMOD to raise awareness about the accelerating impacts of climate change on Himalayan glaciers.

As part of the tribute, two granite memorial plaques inscribed in Nepali, English, and Tibetan were installed near the glacier, serving as a lasting reminder of its disappearance and the importance of protecting mountain environments.

Yala Glacier has also been added to the Global Glacier Casualty List, which recognizes glaciers that have disappeared or no longer behave as active glaciers. It is the only glacier in the Hindu Kush Himalayan region to be listed. 

Scientists warn that if current warming trends continue, much of its remaining ice could vanish by around 2040.

Today, this dead glacier has become a powerful symbol of climate change and the urgent need to protect the glaciers that supply freshwater to millions of people across the Hindu Kush Himalayan region.

What Does a “Dead Glacier” Mean?

A glacier is considered “dead” when it no longer moves under its own weight. Healthy glaciers constantly accumulate snow, form new ice, and slowly flow downhill because of gravity. This movement allows them to renew themselves over time.

When a glacier loses too much ice, it stops flowing and can no longer maintain this natural cycle. Although patches of ice may still remain, the glacier is no longer active and continues to shrink until the remaining ice melts away.

It still has ice today, but scientists say it no longer acts like an active glacier. The official declaration means it has stopped moving, not that all the ice is gone.

Yala Glacier Plays an Important Role in Climate Research

Yala Glacier is one of the most closely monitored glaciers in the HKH. Since 2011, ICIMOD has used it as a benchmark glacier to study how climate change is affecting Himalayan ice.

Scientists often measure changes in the glacier’s size, thickness of ice, snow cover, and mass balance. They use GPS, weather stations, drones, and satellite images to observe changes over time. This information helps researchers understand glacier retreat and improve climate and water models for the future.

This benchmark glacier also serves as a training site for glaciologists from countries across the Hindu Kush Himalayan region, including Nepal, India, Pakistan, China, Afghanistan, and Bhutan.

Its relatively easy access from Kyanjin Gompa allows scientists to carry out fieldwork more efficiently than at many remote Himalayan glaciers. The long-term data from Yala Glacier has made it an important reference point for glacier research in Asia.

Seasonal Glacial Conditions

Yala Glacier changes a lot with the seasons, so visitors have different experiences depending on the time of year.

Spring (March to May)

Spring is one of the best times to visit Yala Glacier. The weather is stable, mountain views are clear, and daytime temperatures are comfortable for trekking. Snow often stays on the upper slopes, making a bright contrast with the nearby peaks.

Summer/Monsoon (June to August)

During the monsoon season, heavy rain and clouds make it hard to see the mountains. Trails can get muddy and slippery, and landslides sometimes affect travel in the Langtang region. Because of this, fewer trekkers visit the glacier during these months.

Autumn (September to November)

Autumn has the clearest skies and the best mountain views of the year. The weather is dry, and temperatures are comfortable, making it the most popular time for trekking to Yala Glacier and climbing Yala Peak.

Winter (December to February)

Winter brings cold weather and fresh snow to the upper Langtang Valley. The glacier and nearby landscape are covered in snow, making for beautiful views. But icy trails and freezing temperatures can make hiking challenging.

Overall, spring and autumn have the best weather and are the best times for trekking.

Wildlife Around Yala Glacier Has Adapted to Harsh Himalayan Conditions

Even though the climate is tough, the area around Yala Glacier is home to many animals that are used to living at high altitudes. Most of them live on the rocky hillsides, grassy meadows, and shrubs near the glacier, not on the ice itself.

You can often spot Himalayan tahr and blue sheep (bharal) in the area, while the snow leopard, which is hard to see, lives higher up as the top predator. Other animals in the Langtang Himal include the Himalayan musk deer, red fox, and Himalayan marmot.

There are also many kinds of birds. People visiting the area might see the colorful Himalayan monal, which is Nepal’s national bird, as well as snow pigeons, yellow-billed choughs, and Himalayan griffons flying over the valley.

Alpine Plants Continue to Grow Around the Glacier

The slopes surrounding Yala Glacier support a variety of alpine plants adapted to the cold Himalayan environment.

Lower elevations feature forests of rhododendron, Himalayan birch, blue pine, silver fir, and juniper. Closer to the glacier, the vegetation becomes sparse, with alpine grasses, sedges, mosses, and lichens growing among rocky terrain.

During the short summer season, colorful flowers such as primulas, gentians, edelweiss, potentilla, and Saussurea bloom across alpine meadows.

The region also contains medicinal herbs, including Himalayan valerian (Valeriana jatamansi), Kutki (Picrorhiza kurroa), and Atis (Aconitum heterophyllum).

Yala Glacier vs Yala Peak

Many visitors mix up Yala Glacier and Yala Peak, but they are two different natural features in the same part of the Langtang Valley.

Yala Glacier is a high-altitude glacier known for its scientific value and role in research. Yala Peak is a 5,732 meter/ 18,806 ft trekking peak that attracts climbers looking for an easier Himalayan summit.

The glacier is often part of the route to Yala Peak, which is why both names often appear together in trekking plans.

Attractions and Views

Visiting Yala Glacier is more than just seeing a Himalayan glacier up close. The trail goes through high alpine areas with wide views of snowy peaks, rocky moraines, and glacial valleys.

A major highlight is the view of Shishapangma (8,013 m), the last mountain over 8,000 meters that is completely in Tibet. On clear days, you can see its summit from near Yala Glacier, adding to the amazing scenery.

The glacier is also surrounded by well-known peaks like Langtang Lirung, Gangchempo, and Naya Kanga, making it a great spot for photographers and mountain lovers.

Most people start their hike from Kyanjin Gompa, a mountain village famous for its monastery, yak cheese factory , and great Himalayan views. Many trekkers visit the glacier along with nearby viewpoints or continue on to Yala Peak for a longer trip.

What Yala Glacier Tells Us About the Himalayas

Yala Glacier is beyond just a hike on the Langtang Valley Trek. It plays an important role in Himalayan glacier research and has become a global symbol of how quickly mountain glaciers are changing.

Even though it was officially declared “dead” in 2025, the glacier still draws trekkers, climbers, and researchers to the upper Langtang Valley.

Its easy access, mountain views, and scientific importance make it one of the region’s most remarkable natural landmarks.

For anyone visiting Langtang National Park, Yala Glacier is a chance to see a unique Himalayan landscape and learn about the changes affecting glaciers in the Hindu Kush Himalaya.
