On an island known for awe-inspiring natural wonders, Arch Rock is Mackinac’s most iconic. This seemingly delicate natural bridge “excites the wonder of all beholders” as it defies gravity, rising more than 140 feet above the waters of Lake Huron. Whether you gaze up from the lakeshore or peer down from the adjacent cliffside, the views that your breath away have been enjoyed by visitors for centuries.

  The first known description of Mackinac Island’s geological formations was penned by Dr. Francis LeBaron on October 30, 1802. The doctor recently arrived at Fort Mackinac to assume the duties of post surgeon. In a letter to the editor of Boston’s Columbian Centinel & Massachusetts Federalist, he wrote:

Dr. Francis LeBaron

 “The island of Michilimackinac is about three miles long and two wide, situated in the straights that join lake Huron to lake Michigan…
The curiosities of this place consist of two natural caves, one of them is formed in the side of a hill, the other in a pyramidical rock of eighty feet in height, and thirty-five feet in diameter at its base, which is situated on a plain and totally detached from any rock or precipice… There are also two natural arches of the Gothic order which appear to have been formed by some convulsions in nature, one is eighty feet in height, the other is forty.”

  Arch Rock received even broader attention in 1812, when a short description appeared in the sixth edition of Reverend Jedidah Morse’s American Universal Geography. Known as the “father of American geography” (also father of Samuel Morse, inventor of the telegraph) his books influenced the educational system of the United States, being widely used in classrooms for decades. In part, his description of Michigan Territory reads:

Rev. Jedidiah Morse

The American Universal Geography, 1812

 “Islands. The island Michilimackinac lies between Michigan and Huron, and is 7 miles in circumference….The fort is neatly built, and exhibits a beautiful appearance from the water… On the N.E. side of the island, near the shore, and 80 feet above the lake, is an arched rock. The arch is 20 feet in diameter, at the top, and 30 at the base… The island is one mass of limestone, and the soil is very rich. The climate is cold but healthy. The winter lasts for 5 months with unabated rigor.”

  After the War of 1812, American military surveys and inspections produced a flurry of descriptions, sketches, and maps of Mackinac Island. During an 1817 survey, Lieutenant William Sanford Eveleth, U.S. Corps of Engineers, composed a highly detailed map, including miniature drawings of Arch Rock, Sugar Loaf and Skull Cave. One can imagine curious visitors strolling each dotted pathway through the woods, in search of geological wonders.

  While sharing his reflections on the arch, Captain David Bates Douglass later revealed, “Several officers have walked over it, among which are Lieutenant Curtis and Pierce and my lamented friend Evelyth, at the dizzy height of 147 feet. However, I should think it a rash enterprise.” [In October 1818, Lieut. Evelyth tragically drowned in a violent Lake Michigan gale during the wreck of the schooner Hercules with all hands lost.]

  Major Francis Smith Belton completed the first known artistic rendering of Arch Rock in September 1817. Also on a military inspection tour, his view is shown from a boat offshore, rendered wild, exaggerated and fantastical.

  One of the two tiny figures drawn at the top of Belton’s image may be Judge Advocate Samuel A. Storrow, who was also on the Island that September. His written description of Mackinac Island and Arch Rock was published as a pamphlet entitled, The North-West in 1817: A Contemporary Letter. In part, it reads:

 “On the eastern side, I found one of the most interesting natural curiosities I have ever witnessed. On the edge of the island, where as elsewhere, the banks are perpendicular, you creep cautiously toward the margin, expecting to overlook a precipice; instead of which you find a cavity of about 75 degrees descent, hollowed from the direct line of the banks; and across it on the edge of the precipice… an immense and perfect arch. Its height is 140 feet from the water, which is seen through it… Looking from the interior, the excavation resembles a crater; but, instead of an opposite side, presents an opening, which is surmounted by this magnificent arch… When on the beach below, you see this mighty arch 140 feet above you, half hid in trees, and seemingly suspended in the air… From the Lake it appears like a work of art, and might give birth to a thousand wild and fanciful conjectures.”

  From these early, enthusiastic descriptions it’s clear that Arch Rock has cast a spell upon Mackinac Island visitors for centuries. To learn more about Arch Rock and the Island’s other natural wonders, watch for future blog posts, exhibits and publications and visit mackinacparks.com.
