Indigenous people

Indigenous people of eastern Greenland carved wood into 3D shapes mimicking coastlines, creating 'Ammassalik maps.' Since paper maps were impossible to read in the snow, these tactile maps let navigators feel the terrain by touch alone.

The world's first sunglasses were invented about 2,000 years ago by Arctic indigenous people. They carved animal bones or ivory to fit the face with thin slits, preventing snow blindness from UV rays reflected off the snow.
