Considering what I just found out about Ojibwe it would appear that way.

The Midewiwin Society is well respected as the keeper of detailed and complex scrolls of events, history, songs, maps, memories, stories, geometry, and mathematics.

from ozhibii'iwe (/o/ + /zhibii'/ + /iwe/), meaning "those who keep records [of a Vision]"
[link to en.wikipedia.org]

May be worth looking into those scrolls and pictographs/petroglyphs as well as myths and stories.
