Magnetic North has moved about 10 minutes

Here is a good short read on the earth's magnetic field, it's origin, and geomagnetic reversals: www.geomag.bgs.ac.uk/reversals.html

From the article Gary linked to:
Human beings have been on the Earth for a number of million years, during which there have been many reversals, and there is no obvious correlation between human development and reversals. Similarly, reversal patterns do not match patterns in species extinction during geological history.

I hypothesize that we are exhibiting an obvious correlative pattern... in the growth of the number of telemarkers.

Not according to some religious groups. In their view we have only been here 6,000 years and we wandered around with the dinosaurs who created a hell of a scene on the Ark and had to be thrown off with the telemarkers who were causing trouble as well.

I guess I'm confused, Larry. What's your base? Somewhere up in Canada? I used the link you provided - www.ngdc.noaa.gov/geomagmodels/struts/calcDeclination - using my Kirkland, Washington, base and came up with very different figures.

The amount of movement was only about 10 minutes per year, not a full degree, and the figure for declination was different by more than half a degree. Starting from today's date, 09-08-09, I get:

2009 17*2' E
2008 17*13' E
2007 17*23' E

Obviously, if we're just trying to figure out where we are on the mountainside, that's not going to make any difference. If we're trying to locate a hundred year old property boundary, it could make quite a bit.

I'm guessing that your last figure should have been dated "1997"?

If you have accurate data from 2997, I wanna see that!!!

:red face emoticon: Thanks. I'm not the greatest typist ....... or editor.

However, 2007 is the right date. NOAA says the magnetic pole is shifting west about 10 minutes a year.
