Keweenaw History and Heritage

Search for people and places. Map your history. Add your story. The Keweenaw Time Traveler brings regional archives to life. 

Keweenaw Time Traveler

The Keweenaw Time Traveler (KeTT) is an online interactive historical atlas that is changing how we learn about, share, and research the history and heritage of Michigan’s Copper Country.

The Keweenaw Time Traveler is a prime example of what can be done with history and technology at a flagship technological university like Michigan Tech.

About the Project

Based in the Historical Environments Spatial Analytics Lab (HESAL) in Michigan Tech's Department of Social Sciences, the KeTT team works with local historical societies and heritage organizations including Keweenaw National Historical Park, Michigan Tech Archives and Copper Country Historial Collections, Carnegie Museum of the Keweenaw, and the historical societies of Houghton, Keweenaw, and Ontonagon counties.

Researchers and community groups in HESAL work together using geospatial technologies to understand how environments change over time. The lab specializes in big datasets, web-based and mobile GIS (geographic information systems), and spatial analysis.

The technology allows everyone to explore social, human built, and natural environments, sparking conversations and illuminating history.

Citizen historians are invited to document building use or transcribe a map.

Find out how to share your story using the Time Traveler Explorer App.
