Key facts

The National Oceanic and Atmospheric Administration (NOAA) identified prehistoric hunting structures at the Alpena-Amberley Ridge beneath Lake Huron.
The site contains stone structures, artifacts, and environmental remains estimated to be at least 9,000 years old.
The discovered stone hunting drives and blinds were used for organised caribou hunts.
Researchers utilised multibeam sonar surveys, Remotely Operated Vehicles (ROVs), and scuba divers to map and inspect the lake floor.
The project aims to create virtual reality models of the Alpena-Amberley Ridge as it appeared during the prehistoric era.
