A historical quarry route without a verified current operator
This entry preserves an old route north of the Mackinac Bridge toward a flooded quarry at the end of Jamison Road. No current owner-approved swimming entrance or operating bathing facility has been established. The saved Mackinaw City match identifies the town, not the quarry.
A road ending at water is not permission
Do not interpret the historical I-75/M-134 and St. Ignace Road route as an invitation to enter a quarry. Confirm the owner, legal entrance and parking before travel; respect gates and posted boundaries.
Remove assumed parking and deep-water attractions
The previous live directions advertised quarry parking and scenic swimming without a current operator source. No maintained entry, surveyed depth or jumping permission is verified. Flooded quarry edges and submerged rock are not a substitute for an inspected bathing beach.
Use DNR guidance only for general safety
Michigan's beach-safety guidance explains changing water hazards at managed beaches. It does not designate Jamison Road Quarry as state-owned, establish a swimming flag system there or grant permission. Choose a confirmed managed destination if quarry access cannot be verified.

Frequently Asked Questions About Jamison Road Quarry
Is Jamison Road Quarry a managed public beach?
No current operator or public bathing designation has been established. The old road description alone is not access permission.
Does the Mackinaw City match locate the quarry?
No. It identifies a locality rather than the quarry's specific entrance, owner or bathing facilities.
Can we park at the end of Jamison Road?
Current visitor parking and lawful entry have not been confirmed. Do not bypass gates or enter private quarry grounds.
Is the water deep enough for diving?
No depth or landing inspection is verified. Do not dive or jump from quarry walls.
Does Michigan DNR's beach guidance mean this is state land?
No. That source provides general water-safety context, not ownership or swimming permission at this quarry.
Can we stay overnight there?
No quarry camping permission is established. Arrange an authorized campground separately.
