Rare Indonesian Tropical Glacier Immortalized in 3D Before Total Disappearance

Published on May 31, 2026

Last November, explorer Klaus Thymann ventured to Indonesia’s remote highlands, home to some of the last remaining tropical glaciers on Earth. At nearly 15,000 feet, these icy remnants are hidden away and largely unrecognized, but they face an imminent threat.

Thymann fears that these glaciers could vanish within a decade due to intensifying climate change. Traveling to the summit of Puncak Jaya, he crafted a detailed 3D model of this unique environment, revealing the urgency of their preservation.

Reaching the glaciers required not only patience but also navigating a perilous landscape. With heavy cloud cover obstructing satellite images, Thymann utilized drones and advanced geolocation technology to document the East Northwall Firn glacier extensively—a site now only a fraction of its former size, with two out of six glaciers already lost.

The resulting 3D model serves as both a scientific resource and a cultural testament. For local communities, these glaciers are considered “eternity” ice. Thymann’s documentation allows future generations to appreciate a natural wonder that is rapidly fading from existence.
