If you're not paying attention you might just miss this important geographical marker because it is disproportionately small - considering its significance.
The 45th parallel (45 degrees north latitude) is the geographic midpoint between the equator and the north pole. Which happens to be just north of Jacksonport on the peninsula.
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 is approximately 3105 miles.
The North Star - Polaris - is directly above the north pole. Therefore the angle between this point and Polaris is 45 degrees.
