The final ice from Slovenia’s Triglav glacier has disappeared, representing a significant loss for the nation where the mountain holds central cultural importance. The glacier, located on the country’s highest peak, underwent dramatic decline over recent decades. Historical records indicate the ice mass covered approximately 40 hectares during the mid-1800s, shrinking to 14 hectares by 1946 when formal scientific measurements began. Between 1983 and 2003, it lost 93% of its surface area, reducing to less than one hectare of exposed rock.
Rather than disappearing entirely, the glacier managed to persist for two additional decades in diminished form, defying earlier scientific expectations about its imminent demise. However, the past five years—a period encompassing three of Europe’s hottest years on record—accelerated the ice loss dramatically. By the end of the recent summer, only isolated pockets remained, with the main body measuring just several meters. Photographs taken following October snowfall confirm complete disappearance of all remaining ice.
Matija Zorn, director of the Anton Melik Geographical Institute and a researcher who began taking measurements at the site in 2001, documented the accelerating pace of melting. He described being shocked each year by the extent of additional ice loss, noting that the location where he needed crampons for safe passage continuously shifted backward as the glacier receded. In one particularly striking example, ice that measured approximately 5 metres deep during a 2022 sampling expedition had vanished entirely by the following year.
The glacier’s disappearance carries significance beyond scientific measurements. Triglav holds central importance in Slovenian national identity, and climbing the peak represents a cultural expectation for residents in this nation of mountain enthusiasts. The loss also eliminates an important climate change indicator that researchers had relied upon for decades.
The Triglav glacier represents part of broader Alpine devastation linked to intense European heat this year. Swiss glaciologists documented that nearly one-fifth of Switzerland’s glacial ice vanished over the past five years, with a 5.5% volume decline in 2026 alone. Scientists characterize the remaining Alpine landscapes as resembling “moonlike” rock deserts. While Triglav’s ice has vanished, subsurface ice deposits in mountain caves have been exposed by the retreat, and a second glacier on nearby Skuta mountain, which remains better shaded, is expected to persist for several additional years.
