Tue, 24 Mar 2026 00:00:00 GMT

The Nyanheka word eleva means "hole in the rock," and the village of Leba took its name from the crevice that opens in the dolomite at 1,757 meters on the western edge of Angola's Humpata Plateau. Inside that crevice, a tube-shaped passage narrows to just six meters wide before descending three meters below the entrance and dead-ending in debris. It is not a grand cave. But within its fifty meters of depth, generations of early humans left behind stone blades, worked points, and half-finished blanks crafted from chert and quartz scavenged from the Leba River's fluvial deposits. The tools span an immense arc of time, from the Acheulean through the Middle and Late Stone Ages into the Iron Age, making this modest opening one of southwestern Africa's most important archaeological windows.

In February 2018, new excavations began under the direction of Daniela de Matos, ending a hiatus that had lasted since the 1970s. The gap is a reminder of what war costs beyond the obvious toll. Decades of potential discovery were lost, field notes vanished, and the continuity of...
