Allowed
Petoskey State Park
Michigan, Emmet·Rockhounding
Petoskey stones may be collected at Petoskey State Park with no permit, but Michigan caps rocks and fossils from all state land at 25 pounds a year.
- No collecting permit exists or is needed — a Recreation Passport is required only for vehicle entry
- State land rule R 299.922(hh) caps removal at an aggregate 25 pounds per person per year of any rock, mineral specimen or invertebrate fossil — a Petoskey stone is a fossil coral, so it counts toward the same 25 pounds as every other rock you keep
