The History and Legend of Arch Rock

Arch Rock is a natural limestone geological formation that developed during the Nipissing post-glacial period, which occurred about 7,500 years ago. At that time, Lake Huron sat at a much higher level. Arch Rock is a unique formation because the type of limestone — breccia — is rare in the Great Lakes region. Also, the arch took thousands of years for it to form. Erosion of the rock continues because it’s porous, which allows moisture to enter through cracks, freeze, and expand. In fact, this process is how most cave systems are created.

The Native Americans believed Arch Rock Mackinac Island to be a place of spiritual power. Some of them viewed it as a bridge to another realm where departed spirits could find a resting place in the island’s caves after death. However, there are many legends and stories about it. One is about a young woman who waited for her lover to come home after battle, but when his tribe returned without him, she leapt off the cliff to join him. Another legend is about a Master of Life who was greatly offended by an Ottawa chief’s shameful act, so he turned the sun red and sent it toward the island, creating the hollowed-out appearance of the rock.

When Euro-Americans arrived on Mackinac Island, they didn’t believe the legends and stories. Instead, they were simply curious and in awe of Arch Rock. In August 1831, Alexis de Tocqueville wrote that it has an “extraordinary shape.”

A New Visitor Center Proposed

Currently, there’s a restroom facility near the Arch Rock site, but it’s 50 years old and could use some upgrades. Governor Gretchen Whitmer has proposed replacing it with fully accessible restrooms and adding a visitor center with geology exhibits and other information about the park. Although there’s no time frame for the project, the new governor wants to name the new facilities after former Governor William G. Milliken, who spent quite a bit of time on Mackinac Island in the governor’s summer residence and at his own cottage after his service in office.

The Location of Arch Rock on Mackinac Island

Arch Rock Mackinac Island rests on the southeast part of the island. Its uniqueness is one of the reasons why locals pushed for the island to become Mackinac National Park, which occurred in 1875 and made it the second national park after Yellowstone. Although it became Mackinac Island State Park in 1895, making it the first Michigan state park, the rock formation has always been a protected part of it.

Currently, the state park encompasses 1,800 acres, which is about 80% of the island, including permanent residences, Mackinac Island Airport, and many important geological and historical features. The park welcomed its 20-millionth visitor on July 15, 2009.

Photos of Arch Rock Mackinac Island

Since the first European-Americans to be on Mackinac Island viewed Arch Rock as a geological curiosity, there are photos of the soldiers and residents sitting and standing on it. Today, though, climbing onto the natural limestone arch is strictly prohibited for everyone’s safety and its structural integrity. Instead, there’s a platform that you can stand on. It gets pretty close and offers sweeping views from Arch Rock of Lake Huron and Canada.

Things to Do Near Arch Rock

There are quite a lot of things to do on Mackinac Island that are near Arch Rock. Here are a few of the closest and (in our opinion) most interesting attractions to visit.

Dwightwood Springs

Below the formation on M-185 is Dwightwood Springs. Of the other springs across the island, this one is the most popular, probably because the clear, cold water flows at the bottom of the stair trail to Arch Rock. There are benches and a pergola at the site, and everything there is dedicated in memory of Dwight Hulbert Wood, who sacrificed his life in a 1905 accident, saving his brother in the process.

The Forts

Fort Mackinac served as a military outpost and residence between the late 18th and late 19th centuries. The British built it during the American Revolutionary War to control the straits and fur trade. Later, it was the scene of two battles between the British and U.S. Army during the War of 1812 for control over the Great Lakes. Now, it’s a museum with very interesting exhibits.

Situated on Mackinac Island’s highest point, Fort Holmes is a supplementary fortification originally built in 1814 by the British during the war. The foreign soldiers used it to defend Fort Mackinac against the U.S. Army.

Skull Cave

A small and shallow cave, Skull Cave is the hiding place that Alexander Henry, an English fur trader, used while surviving the Pontiac’s War of 1763. Now part of Mackinac Island State Park and a intriguing photo stop, the cave used to be a graveyard.

With the third-oldest live butterfly exhibit in the country, The Original Mackinac Island Butterfly House and Insect World is a world-renowned, 1,800-square-foot facility. It has a tropical garden and hundreds of butterflies from four continents.

  1. Caves form in limestone when water, containing minute amounts of acidity flows through cracks and fault systems. The hcl reacts with the Ca CO3 of limestone and dissolves the rock. Later, those same limestone molecules will precipitate out of solution and form an underground cave formation over eons of time. Freeze thaw, which causes expansion and contraction of naturally broken up rock (breccia). This movement causes gravity erosion and water and wind erosion of the exposed rock to occur. Its called spalling when its a solid rock like granite.

  2. This was a great article. Thank you for making me miss the U.P. (I’m not even from there, and visited once).

  3. I found the crack in the middle of the island to be more incredible. Strange it is just there.
