The Great Lakes Indian Fish and Wildlife Commission is an invaluable resource for finding maps (we use Gidakiiminaan as a starting point to supplement location names and stories from Elders).
The GLIFWC periodical keeps us up to date on local issues, including water protection and Ojibwe language. You can find all issues on their website or order them to be delivered.
Lakehead University has collected a lot of resources to explore! Some pronunciations and names may be different, as always respect the knowledge of your local Elders.
