Balletto Glacier

The Balletto Glacier is one of the lesser-known glaciers on the southwestern side of Kibo, Mount Kilimanjaro’s highest cone, part of the rugged ice complex around the great Breach Wall. Overshadowed by its famous neighbours — the Heim and Diamond glaciers — it is nonetheless part of the wild, seldom-visited western face that reveals a very different Kilimanjaro from the one most trekkers know.

Quiet and remote, the Balletto Glacier is a reminder that the mountain’s ice extends well beyond its famous summit views, onto steep and dramatic ground rarely seen up close.

Overview of the Balletto Glacier

The Balletto Glacier is a southwestern-flank glacier, part of the ice found on the steep western side of Kibo near the Breach Wall. It lies among the cluster of western and southwestern ice features — alongside the Heim Glacier and, higher up, the hanging Diamond Glacier — that together make this the most rugged and mountaineering-oriented side of the mountain.

Like all of Kilimanjaro’s ice, the Balletto Glacier is thinning and retreating, its margins marked by the vertical ice walls that are characteristic of the mountain’s glaciers.

Where Is the Balletto Glacier Located?

The Balletto Glacier lies on the southwestern side of Kibo, in the area of the Breach Wall, on the steep and rugged western face away from the standard summit routes.

Key location details:

• Mountain: Mount Kilimanjaro (Kilimanjaro National Park)
• Position: Southwestern face of Kibo, near the Breach Wall
• Neighbouring glaciers: Heim and Diamond
• Nearby route: the Western Breach
• Elevation: high on the western face, toward the crater rim near 5,700 m
• Status: remote, retreating glacier

Part of the Breach Wall Ice Complex

The southwestern face of Kibo is dominated by the Breach Wall, a great cliff whose ice features have drawn some of the boldest mountaineers to Kilimanjaro. The Balletto Glacier is part of this complex of western ice — a quieter companion to the celebrated Heim Glacier below the wall and the glittering Diamond Glacier hanging near its top.

Where most of Kilimanjaro’s ice sits on gentle summit plateaus or the sunlit southern face, the western ice occupies steep, broken ground, making it far less accessible and far less often seen. The Balletto Glacier belongs to this wild side of the mountain.

Size, Elevation, and Conditions

The Balletto Glacier lies in Kilimanjaro’s arctic summit zone, where the air stays permanently below freezing while the equatorial sun is fierce.

Conditions on the ice:

• Surface temperatures remain below freezing year-round, from a few degrees below zero by day to well under −15 °C on cold, clear nights.
• Its steep western position is exposed to intense direct sunlight, which erodes the ice.
• Precipitation falls as snow and graupel and often disappears within days.
• The glacier has no active accumulation zone, so it loses more ice than it gains.

A Retreating Glacier: Ice Loss on Kilimanjaro

The Balletto Glacier is part of one of the world’s most studied examples of tropical glacier loss. Almost 85 percent of Kilimanjaro’s ice cover disappeared between 1912 and 2011, shrinking from about 11.4 km² to under 1 km².

Key facts about the retreat:

• Average annual ice loss was about 1.1 percent from 1912 to 1953, rising to 1.4 percent (1953–1989) and 2.5 percent (1989–2007).
• Of the ice still present in 2000, nearly 40 percent had gone by 2011.
• The western glaciers, including the Balletto, have thinned and retreated along with the rest of the mountain’s ice.
• One 2013 assessment estimated most of Kilimanjaro’s ice will vanish by around 2040, and that it is highly unlikely any ice body will remain after 2060.

Why the Balletto Glacier Is Retreating

The causes of Kilimanjaro’s ice loss are subtler than simple warming. Research points to a decline in atmospheric moisture — lower specific humidity following a sharp climate shift at the end of the 19th century — rather than rising air temperature as the main long-term driver. No clear warming trend was found at the elevation of these glaciers between 1948 and 2005.

Because the summit air stays below freezing, the ice rarely melts from the top. Instead it is lost mainly through solar radiation and sublimation, where ice turns directly to vapour in the dry, sunlit air. On the steep western face, this steady loss continues to shrink the glacier year by year.

Seeing the Balletto Glacier

The Balletto Glacier is on steep, remote terrain not crossed by the standard trekking routes, but the wild western side of the mountain can be appreciated from nearby.

• The dramatic Western Breach lies on the same rugged western side of the mountain.
• The nearby Heim Glacier and hanging Diamond Glacier form the rest of this ice complex.
• Climbers approaching via Arrow Glacier Camp pass through the wild western side where these glaciers stand.

Why the Balletto Glacier Matters

The Balletto Glacier is a reminder that Kilimanjaro’s ice is more extensive and more varied than the famous summit views suggest. Quiet and rarely photographed, it is part of the wild western face that gives the mountain its mountaineering heritage. Its retreat, like that of its better-known neighbours, is part of the wider story of Kilimanjaro’s vanishing ice.

What the Experience Feels Like

To glimpse the Balletto Glacier and the western ice is to see Kilimanjaro at its wildest — steep walls of rock and ice far from the crowds of the main routes. Even for those who never set foot on this terrain, knowing that such remote glaciers cling to the mountain’s western face deepens the sense of how vast and untamed the roof of Africa truly is.

Frequently Asked Questions About the Balletto Glacier

Where is the Balletto Glacier on Mount Kilimanjaro?

The Balletto Glacier lies on the southwestern face of Kibo, in the area of the Breach Wall, on the steep and rugged western side of the mountain away from the standard routes.

What other glaciers are near the Balletto Glacier?

It is part of the western ice complex alongside the Heim Glacier below the Breach Wall and the hanging Diamond Glacier near its top.

Is the Balletto Glacier retreating?

Yes. Along with the rest of Kilimanjaro’s ice, it has retreated sharply — nearly 85 percent of the mountain’s ice was lost between 1912 and 2011, and most is projected to be gone by around 2040.

Why is the ice retreating if the summit stays below freezing?

Loss is driven mainly by reduced atmospheric moisture, solar radiation on the ice, and sublimation — ice turning directly to vapour — rather than by melting from above.

Can you see the Balletto Glacier when climbing Kilimanjaro?

It sits on steep, remote terrain not crossed by the standard routes, but the wild western face where it lies can be appreciated from the Western Breach and the Arrow Glacier Camp approach.
