I'm curious specifically about the Cree people of Alberta and Saskatchewan pre-colonization.

Indigenous groups in Arctic regions of Canada famously use igloos, seal skin clothing etc., to survive the frigid temps, but the Prairies can often get just as cold and to my knowledge those items aren't a part of traditional Cree life-- so how did they survive?

Edited my post after the mods pointed out my original wording could be construed to mean Cree people no longer live in Western Canada-- apologies for any confusion!
