Mendota (Bete Grise) Light
lighthouse in Michigan, United States

The Mendota Light, also known as the Bete Grise light, was built on the Keweenaw Peninsula of Michigan to facilitate travel between Lake Superior and Lac La Belle (an artificial canal having been made to connect the two).
History
The original plans were laid in 1867 and the lighthouse was constructed in 1869. Only one year later, the light was decommissioned as it was found by navigators to be of no assistance (nor was there any other commercial reason to make this trip).
The tower was removed and taken to Marquette, but the keeper's house remained in place. In 1892, ships tried to use this bay for a safe harbor during a storm, and the seafarers, observing the house (at this point deserted), suggested that the harbor would be easier to find if there was a light present. By 1895, funds had been allocated to re-establish the light, but it was determined that the existing structure had deteriorated so much that it could not be used. A new structure was built using the original foundations.
In 1933 the light was automated and in 1956 it was decommissioned.
It was a private residence until 1996. The lighthouse, only accessible by boat since no roads or private drives lead to it, was for sale in 1996.

Why this record matters
The phrase “lighthouse in Michigan, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q6816728. Authority coordinates are 47.374, -87.967. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1867, 1869, 1892 and 1895.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
