Core atlasMICHIGAN CITY ROCKHOUNDING HUB
Keweenaw copper country, volcanic rocks and restricted historic mining areas.
LOCAL INTERACTIVE MAP
Explore nearby Michigan records without leaving this hub. Status, coordinate precision and access evidence determine whether a pin is a realistic field destination.

Reference photograph used for rock and mineral identification. It is not from this exact location or a guarantee that collecting is permitted.
This hub uses Houghton as a geographic base, while the material mix is calculated from the records actually mapped around it.
Records are ordered by evidence status first, then distance. Open the detailed guide before treating any pin as a trip destination.
