Glaciers Near Uhuru Peak Summit
The glaciers of Kilimanjaro, including the prominent Furtwängler, Rebmann, Credner, and Arrow glaciers, are nestled within the mountain’s northern and southern icefields. These icefields, once protective shields for the glaciers, are themselves diminishing, exposing the ice to further melting and sublimation—a process where ice transforms directly into vapor without becoming liquid. This phenomenon, driven by the intense equatorial sun and changing climatic patterns, underscores the fragility of these natural wonders. For those who trek to Uhuru Peak, the glaciers offer a breathtaking yet sobering glimpse into the impacts of global warming. High above the equatorial plains of Tanzania, Mount Kilimanjaro stands as Africa’s tallest peak, its summit crowned by a rare and vanishing spectacle: tropical glaciers. These ancient ice formations, found only in a handful of locations near the equator, are a testament to the planet’s climatic diversity. Alongside Mount Kenya and the Rwenzori Mountains, Kilimanjaro hosts some of the last remaining tropical glaciers in Africa. However, these icy relics, sculpted over millennia, are under severe threat from accelerating climate change. Rising temperatures, shifting humidity, and reduced snowfall are causing Kilimanjaro’s glaciers to retreat at an alarming rate, with some projections estimating their complete disappearance within the next few decades. For adventurers and nature enthusiasts, the opportunity to witness these glaciers near Uhuru Peak—the mountain’s summit at 5,895 meters—is both a privilege and a race against time.
Key Glaciers Near Uhuru Peak
Furtwängler Glacier
- Location: Near Uhuru Peak, within the crater of Kilimanjaro’s Kibo summit.
- Description: The Furtwängler Glacier is Kilimanjaro’s most iconic and largest remaining glacier, though its size has dwindled dramatically over the past century. Named after Walter Furtwängler, a climber who reached the summit in 1912, this glacier is a stark symbol of climate change’s toll. In 1976, it spanned 113,000 square meters, but by 2000, it had shrunk to just 11,000 square meters—an astonishing 90% reduction. By 2011, approximately 85% of the glacier had vanished. Its ice, estimated to be 11,700 years old in some areas, is succumbing to sublimation, exacerbated by reduced snowfall and warmer temperatures. The glacier’s proximity to Uhuru Peak makes it a focal point for climbers, who can stand near its shrinking ice walls and witness its rapid retreat firsthand.
- Estimated Extinction: As early as 2030, though some projections extend to 2060.
- Significance: The Furtwängler Glacier’s plight has drawn global attention, with climbers and scientists alike documenting its decline. Its loss will not only alter Kilimanjaro’s landscape but also impact local ecosystems and tourism-dependent communities.
Rebmann Glacier
- Location: Positioned near the Southern Icefield, accessible via routes approaching Uhuru Peak.
- Description: Named after Johann Rebmann, the German missionary-explorer who first documented Kilimanjaro’s glaciers in 1848, the Rebmann Glacier is one of the mountain’s most historically significant ice formations. Located on the southern slopes of Kibo, it is partially shielded by the Southern Icefield, which has slowed its retreat compared to other glaciers. However, the glacier is still shrinking rapidly, with its once-expansive ice now reduced to fragmented remnants. Climbers on routes like the Machame or Umbwe may catch glimpses of Rebmann’s glistening ice, a reminder of the mountain’s frozen past. Studies indicate that its ice, like that of other Kilimanjaro glaciers, dates back thousands of years, but its vulnerability to sublimation threatens its survival.
- Estimated Extinction: Likely within the 2030–2060 timeframe, alongside other Kilimanjaro glaciers.
- Significance: The Rebmann Glacier’s historical connection to early European exploration adds a cultural dimension to its environmental importance, making its preservation a priority for conservationists.
Credner Glacier
- Location: Situated near the Northern Icefield, on the northwestern slopes near Uhuru Peak.
- Description: The Credner Glacier ranks among Kilimanjaro’s largest surviving glaciers, though it too is retreating at an alarming pace. Located in the Northern Icefield, it benefits from slightly cooler conditions on the mountain’s northern slopes, but this has not been enough to halt its decline. Research, including studies supported by the Smithsonian Institution, suggests that the Credner Glacier could vanish before 2030. Its ice walls, once towering and robust, are now thinning, with significant portions lost to sublimation and reduced snowfall. Climbers on the Rongai or Northern Circuit routes may encounter this glacier, marveling at its stark beauty while confronting the reality of its imminent loss.
- Estimated Extinction: Before 2030, based on current trends.
- Significance: The Credner Glacier’s rapid retreat underscores the vulnerability of even the most resilient glaciers to climate change, serving as a critical case study for glaciologists.
Arrow Glacier
- Location: Found along the Lemosho Route, near the Western Breach approach to Uhuru Peak.
- Description: The Arrow Glacier, once known as the Little Barranco Glacier, is a small but poignant remnant of Kilimanjaro’s glacial past. Located on the western slopes, it is one of the most endangered glaciers, with some reports suggesting it may already have disappeared by 2025. Its diminutive size and exposure to the equatorial sun have accelerated its demise, making it a stark example of the irreversible impacts of global warming. Climbers on the Lemosho Route may pass by the glacier’s former site, where only traces of ice remain, if any. The Arrow Glacier’s near-total loss highlights the urgency of witnessing Kilimanjaro’s glaciers before they are gone forever.
- Estimated Extinction: Likely already vanished or imminent by 2025.
- Significance: The Arrow Glacier’s disappearance serves as a somber warning of the fate awaiting other Kilimanjaro glaciers, emphasizing the need for immediate climate action.
A Call to Action for Climbers
For those planning to summit Kilimanjaro, the glaciers near Uhuru Peak offer a rare opportunity to witness a vanishing natural wonder. However, this privilege comes with a responsibility to tread lightly and advocate for change. Avoid activities like ice climbing, which can damage the fragile glaciers, and instead focus on documenting their beauty through photography. Sharing these images can raise global awareness of the climate crisis affecting Kilimanjaro and other vulnerable regions.
When booking a trek, choose operators committed to sustainability, such as those prioritizing eco-friendly camping and “leave no trace” principles. Responsible tourism can help preserve Tanzania’s natural heritage, supporting local communities while minimizing environmental harm. As Kilimanjaro’s glaciers fade, climbers have a unique role in bearing witness to their beauty and advocating for urgent climate action to protect the planet’s remaining treasures.
