Arch Rock on Mackinac Island

Rising 146 feet above the water, Arch Rock is a natural curiosity which spans fifty feet as its widest point.  It was formed over thousands of years by wind and water eroding soft rock below, leaving only the hard breccia rock which forms the arch.

Arch Rock via Wikipedia

Arch Rock is a geologic formation on Mackinac Island in Michigan. It is a natural limestone arch formed during the Nipissing post-glacial period, a period of high Lake Huron levels following the end of the Wisconsin glaciation. To this day Arch Rock stands on the Lake Huron shoreline 146 feet (45 m) above the water.

Limestone breccia is not an ideal material for natural bridges, and this type of formation is quite rare in the North American Great Lakes region. The Native Americans saw Arch Rock as a place of numinous power, and told many stories and legends about it. >> Read More on Wikipedia >>
