GRSM COMPASS DECLINATION

The difference between the north geographic pole and the north magnetic pole is called magnetic declination or usually just declination. Inclination is the angle of pull down toward the earth that the magnetic field exerts on a compass needle. At the north magnetic pole, the north end of the needle is pulled straight down toward earth. The corresponding Integration of Resource Management Applications (IRMA) NPS Data Store reference is Great Smoky Mountains National Park Compass Declination.
