Michigan Meridian
From Wikipedia, the free encyclopedia
The Michigan Meridian is the meridian, or the north-south line used as a reference in the Michigan Survey, the survey of the U.S. state of Michigan in the early 19th century.
The meridian was surveyed in April of 1815 by Benjamin Hough. The meridian was selected because it formed one of the principal boundary lines defined in the Treaty of Detroit in 1807, which was the first large cession of land by Native American nations to the United States in Michigan. In that treaty, the boundary line was described as running due north from the mouth of the Auglaize River on the Maumee River, which was the site of Fort Defiance, now Defiance, Ohio.
Michigan's baseline was surveyed at the same time by Alexander Holmes. Although regulations governing the U.S. Public Land Survey System would later specify that the baseline should be a true parallel of latitude, this was not the case in earlier surveys, including the Michigan survey.
The Michigan Meridian forms the boundary between several counties in Michigan: Lenawee and Hillsdale; Shiawassee and Clinton; Saginaw and Gratiot; Ogemaw and Roscommon; Oscoda and Crawford; Montmorency and Otsego; and a portion of the boundary between Chippewa and Mackinac. U.S. Highway 127 approximately follows the meridian from the Ohio border into Jackson. In Okemos, there is a historical village of Meridian, located on the line.
In the area of Ohio known as the Toledo Strip, the townships are numbered from the Michigan Meridian and base line because at the time they were surveyed, the area was considered to be a part of the Michigan Territory.
A ten-mile wide strip of land was given to Indiana when it became a state in 1816. Since this land had not been surveyed, the Indiana portion was surveyed was the rest of Indiana. However in Michigan, the southernmost tier of townships are truncated. The townships were surveyed and sections numbered as if they were in whole townships, except that the southernmost survey townships were only six miles wide and about three and a half miles tall instead of six miles square. Sections 19 through 24 in each township were chopped approximately in half, while sections 25 through 36 simply did not exist for these survey townships. To compensate for the smaller size, some of the civil townships formed from these survey townships were given additional sections of land from adjacent townships, for example White Pigeon Township in St. Joseph County or Three Oaks Township and New Buffalo Township in Berrien County. Some others of these smaller townships were merged into adjoining townships, as in Porter Township in Cass County. Similarly, many of the civil townships in Michigan along the Ohio border have somewhat more or less than the standard 36 square miles.
[edit] Trivia
- There is a long road called Meridian Road which follows the path of the Michigan Meridian; but is however chopped in discontiguous portions. One part of Meridian Road has an interchange on the US-10 freeway, and another part is a freeway overpass over Interstate 96.
