Standout jasper spots in Michigan
Hand-picked from the full list below, with the reason each one earns a trip.
Woodland Park Beach, Grand Marais
Alger County County
Grand Marais is the most famous place in Michigan to hunt Yooperlites, sodalite-bearing syenite stones that glow bright orange under ultraviolet light. Woodland Park provides free public Lake Superior beach to search after dark, where the shoreline below the high-water mark is public land. Lake Superior agates and jasper turn up in the same gravel by day.
Keweenaw Point
Keweenaw County County
The exposed Lake Shore Traps along the wave-washed tip of the Keweenaw Peninsula carry agate-filled amygdules and datolite, with larger Keweenaw agates working loose from a narrow gravel band at the waterline. The State of Michigan and The Nature Conservancy secured public access to roughly 6,275 acres here in 2003, keeping the Point open for shoreline collecting. Thomsonite and chalcedony round out the finds.
Jasper Knob (Jasper Hill)
Marquette County County
Jasper Knob in Ishpeming is a bald hilltop made entirely of jaspilite, a 1.87-billion-year-old banded iron formation of alternating red jasper and silvery specular hematite. The folded, polished bands are among the best easily reached banded-iron exposures in North America. A short foot trail off Hill Street leads straight to the outcrop.
Lake Superior Beach (Ontonagon)
Ontonagon County County
The Lake Superior shoreline around Ontonagon is among the most agate-rich in Michigan, with the stretch toward Copper Harbor noted for unusually heavy agate cover along with quartz, jasper, and occasional copper. Public township and roadside beaches give free access to the wave-sorted gravel where Keweenaw agates and thomsonite turn up. The best searching follows a storm that reworks the gravel.
