The height nobody agrees on
Arch Rock’s height depends on who you ask and when. A geography book published in 1812 put it 80 feet above the lake. A letter written in 1817 said 140 feet from the water. Mackinac State Historic Parks now says more than 140 feet, and the Tourism Bureau says some 145.
The early accounts also say people walked over the top of it. Captain David Bates Douglass wrote that several officers had, at what he gave as 147 feet, and added that he should think it a rash enterprise. Do not repeat it.
The Tourism Bureau says the evidence puts the arch at about 4,000 years old, hollowed out by waves when lake levels were much higher, with the limestone breccia left standing. It says Mackinac National Park was created in 1875 in part to protect Arch Rock. Mackinac State Historic Parks calls that park the United States’ second national park, before it became Michigan’s first state park in 1895.
People have predicted since the 1800s that the arch would fall. The Tourism Bureau calls it a stable formation that should last for the foreseeable future, and also says it will probably come down someday, which is its argument for going now.
Before you go
- Finding it. It is a little way past Mission Point Resort, after Lakeshore Drive veers north.
- Getting there. Ferry from Mackinaw City or St. Ignace. Arnold Transit and Shepler’s both list departures from both towns.
- Ferry cost. Arnold Transit fast ferry: adult round trip $37, adult one way $25, ages 5 to 12 round trip $25, under 4 free. Shepler’s: adult round trip $39, ages 5 to 12 round trip $27. Both add booking fees; Shepler’s lists $2 per ticket.
- On the island. 207 steps up from Lakeshore Drive, or on foot or bike from the interior by Arch Rock Road, which leaves Huron Road behind Fort Mackinac, or on a horse-drawn carriage tour.
- Stay off it. Crossing the arch is illegal now, according to the Mackinac Island Tourism Bureau.
