that animatedknots thing is pretty cool. i was watching the amazing race with my dad and a bunch of people were failing on a challenge because they didn't know how to tie any knots. |
Y, It helped me big-time.
I'm going to print out the magnetic declination instructions for my compass here in case I need to reference them again.

Magnetic Declination
The Magnetic Needle in a compass is attracted by the magnetism of the Earth
and therefore always points to the constantly shifting Magnetic North. There is
another "North Pole." True North is static and located geographically about 800
miles north of the magnetic pole. Maps and directions are usually based on True
North. Magnetic declination is the angle between True North and Magnetic North.
The amount of declination at any given point depends on the location of that
point on the continent. Where True and Magnetic North are in the same direction,
the declination is zero [Chicago]. At any point west of that line, your compass needle will
point east of True North. This is called "Easterly Declination." At any point east of
that zero line, you compass needle will point west of True North. This is called
"Westerly Declination."
[In Northern California it looks like the Easterly Declination is about 15 degrees (based on their map)] |
