Germany's SPK Prussian Cultural Heritage Foundation confirmed Wednesday that its president Hermann Parzinger would hand over the artifacts to envoys of the Chugach peoples due to visit Berlin next week.

The items, including two broken masks, a child's cradle and what is thought to be a shamanic figure, originate from Chenega Island, about 160 kilometers (100 miles) southeast of Anchorage, along the Pacific coastline of the US state of Alaska.

Norwegian adventurer Captain Johan Adrian Jacobsen, who toured Alaska's southwestern coastline in 1883, brought them to the-then Royal Museum of Ethnology, the forerunner of Berlin's ethnological museum within the SPK foundation's cluster of Berlin-based institutions.

"At the time, these objects were taken without the consent of the Alaska Natives and were therefore removed unlawfully from the graves of the deceased, so they do not belong to our museums," Parzinger stated last December.

"From Adrian Jacobsen's travel journal, it is clear that the graves [on Chenega Island] were opened solely for the purpose of removing their contents, said the foundation in December when its board agreed on the returns.

Representing the descendants next week will be leaders of the Chugach Alaska Corporation, which in 2015 with SPK staff began re-examining Prussian collection items.

One of their joint tasks was to create a virtual library of all Chugach objects scattered around the world to enable further study.

The now unpopulated Chenega Island was devastated by Alaska's 1964 Good Friday earthquake and impacted by the 1989 Exxon Valdez oil disaster in Prince William Sound.
