Indiana's northeast corner is marked once again.
Last week, engineers and surveyors mapping the state line from Lake Michigan east found the exact spot where Indiana and Michigan converge. But it wasn't easy: The effort took three tries over nearly four years.
The boundary originally was marked with a white oak post in 1827. But the post had rotted away.
Four trees that another engineer had used to mark the spot in the early 1900s also were gone, leaving surveyors only rough markings to go by.
Jack Owens, who leads the mapping group, tells the Hillsdale Daily News those markings provided the clues surveyors needed.
They found the remnants of the original oak post buried about 15 inches below ground and replaced it with a concrete marker they hope will last for centuries.
