A National Geographic documentary special follows expedition leader Ulla Lohmann to New Guinea to investigate the mystery of ancient mummies [1].

The exploration highlights the unique cultural practices of the Anga people, providing a rare look at how these ancient remains were preserved and displayed. Understanding these methods offers insight into the region's ancestral heritage and the specific environmental factors that allow for such preservation.

Lohmann led the expedition to a specific cliffside gallery where the mummies are displayed [1]. The site serves as a focal point for the study, as the Anga people utilized this high-altitude environment to maintain the bodies of their ancestors. The documentary focuses on the technical aspects of how mummification was practiced in this remote area [1].

The investigation seeks to uncover the lessons of the Anga people and the specific rituals associated with their burial customs [1]. By analyzing the state of the remains and the location of the gallery, the team aims to reconstruct the process used to treat the bodies. The cliffside setting is central to the mystery, as it protects the mummies from certain elements while exposing them to others.

Throughout the special, the focus remains on the intersection of geography and tradition. The expedition documents the physical characteristics of the mummies, and the layout of the gallery, to determine how the Anga people managed their dead over generations [1].

“Expedition leader Ulla Lohmann investigates the mystery of ancient mummies among the Anga people.”

The study of the Anga mummies provides critical data on non-Egyptian mummification techniques, demonstrating how indigenous populations adapted to specific climates to preserve their dead. This research expands the global understanding of ancestral veneration and the biological chemistry of preservation in tropical highlands.
