This c. 1940 image appears to show White Rock, the offshore limestone landmark near the community of White Rock in Huron County, Michigan.
The rock sits in Lake Huron, off the shoreline south of Harbor Beach and north of Forestville. It gave the nearby community its name and is best known for its role as a boundary point in the 1807 Treaty of Detroit. That treaty involved the Ottawa, Chippewa, Wyandot and Potawatomi, who ceded a large area of land in what is now southeast Michigan and northwest Ohio.
The title says the rock was “a bit bigger,” and that fits later accounts noting that ice and weather have broken it down over time. This photo likely preserves a view of the landmark before more of it disappeared into Lake Huron.
Do you remember seeing White Rock from shore, or hearing local stories about it?
