At which North Pole does Santa Claus live? North Referenc e

True North The earth’s axis of rotation

Magnetic North Where your compass points

Grid North Where the UTM grid lines “point” to Grid Nerd

The North Reference you choose determines where 0° is when you measure an angle with your protractor or compass.

True v.s. Magnetic North

What is the difference here? Fruitvale Ave. is aligned with True North. So are the edges of parking lots 4 & 5. Let’s go take a bearing along the edge of lot 4 and see what we get…

Declination Diagrams

Declination changes over time Here in Northern California it changes by about 1° every 20 years. The declination shown on your topo map may be out of date. What about declination displayed by my GPS? –It probably correct as of the date of manufacture.

Local Anomalies May be as much as 90 degrees –3-4 degrees is common North of Kingston, Ontario; 90° of anomalous declination. Kingston Harbor, Ontario; 16.3° W to 15.5° E of anomalous declination over two kilometers (1.2 miles); magnetite and ilmenite deposits. Savoff, Ontario (50.0 N, 85.0 W). Over 60° of anomalous declination. Ramapo Mountains, northeastern New Jersey; iron ore; compass rendered useless in some areas. Near Grants, New Mexico north of the Gila Wilderness area; Malpais lava flows; compass rendered useless.

Check you compass & sighting technique using these methods and the declination for the area Find some place near your home to establish your personal compass testing location. Identify several features, at least 1km away, that you can sight on. Use a map to determine True bearings to these features. Convert these bearings to Magnetic using the calculated declination for the area. Check your compass and technique. Experiment with the your gear to see if it influences your compass. Keep notes, so you can repeat this in the future.
