Picture from ᑮᓈᓕᒃ ᐅᓂ ᖃᑲᒥ (Ernie Eetak) of Arviat: “Waiting for seal and bearded seal … I wear all caribou, including caribou antler sun glasses.”
Caribou bone sunglasses may be referring to something like these!
These are a very old style of anti-glare eyewear developed by people in the far north. Instead of glass, it cuts down on the amount of reflected light coming off the snow by only leaving a thin open strip to see out of. These are often made of bone.
Imagine being this dripped out. ALL caribou outfit, INCLUDING the caribou antler sun glasses.
Sachs has been making boom boxes and sound systems since childhood. For Sachs, the power of sound systems can influence the way we see and experience space.
