This website is aimed at communicating the strong Geoheritage of the western UP, including the Keweenaw Peninsula and Isle Royale.  We aim to reach any reader, and to help them understand:

What is geoheritage?

How does Earth Science guide us and influence our living and culture?

What are the elements of geology here?

What are the places that teach us the Earth history here?

How does the Keweenaw window into Earth’s history contribute to our world view?

As much as anywhere on Earth, the Keweenaw reflects its Geology....

This site is intended to support outdoor exploration and education about the Earth and how it works in an area where there are many strong and informative examples. There is an assembly of basic information in lectures and web materials here, and this is followed by specific field sites, their description, location and geointerpretation. We want to complement and extend other geointerpretation efforts, such as Mineralogical Society: Virtual Keweenaw Field Trip .Try to visit many sites, because they reinforce each other and build geounderstanding. Send suggestions for things that need to be added, changed or deleted.
