Carstensz East

Carstensz East is a mountain summit in Lorentz National Park that rises to 4,820 meters with steep limestone cliffs marking its profile. A small glacier persists near the eastern ridge, creating a striking visual feature.

The peak was named after Dutch sailor Jan Carstensz, who first documented the snow-covered mountains of Papua in 1623. This discovery brought widespread attention to the existence of ice formations in the tropical region.

The mountain holds spiritual meaning for the Amungme people, who view these peaks as dwelling places of their ancestors.

The climb requires technical gear, certified guides, and a permit before attempting the ascent. Conditions are demanding, and the route is suitable only for experienced mountaineers.

This mountain holds one of the last glacier formations in Indonesia, with scientists predicting its disappearance within coming decades. The rapid melting serves as visible evidence of climate change affecting this remote mountain region.
