the 45th Parallel

Door County, Wisconsin

There are two markers to the 45th Parallel on the Door County peninsula, both placed by the Door County Historical Society.

Egg Harbor Park

On the west side, along Highway 42 south of Egg Harbor, look for a county wayside picnic area where this boulder marks the position of the 45th Parallel in Door County (see Halfway to the Pole for more about markers in the area). The plaque reads:

Halfway To The North Pole

The 45th Parallel (45 degrees north latitude) runs through this wayside. This is the midpoint between the Equator and the North Pole. But, because the earth is slightly flattened at the poles, the distance from the 45th Parallel to the North Pole is approximately 3117 miles and to the Equator approximately 3105 miles.

Polaris (North Star) is directly above the North Pole. Therefore the angle between this point and Polaris is 45 degrees.

Meridian Park

On the east side of the peninsula, there is a similar marker attached to a similar boulder, in the aptly named Meridian Park in Jacksonport just north of the 45th Parallel.

Halfway To The North Pole

The 45th Parallel (45 degrees north latitude) runs through a point one half mile south of this wayside (intersection of Hwy. 57 and Logerquist Road). This is the geographical midpoint between the Equator and the North Pole. But, because the earth is slightly flattened at the poles, the distance from the 45th Parallel to the North Pole is approximately 3117 miles and to the Equator approximately 3105 miles.

Polaris (North Star) is directly above the North Pole. Therefore the angle between this point and Polaris is 45 degrees.
