You Completed the Document Building Materials app!

You did it! Citizen Historians have classified the materials of over 60,000 Keweenaw buildings from 1888–1949. That means that every building in the Explore App can be identified as brick, stone, wood, iron or a combination of those materials. All your hard work is already making the Time Traveler more fun for everybody! Thank you.
​
Don't worry—You can still be involved! Citizen Historians can keep working on the Time Traveler. Now, help get more information into the database by transcribing the hand-written map notations, or classifying buildings by their everyday uses. Give it a try!
