Subject: Magnetic declination
From: "Tom Woosnam" <twoos@csus.com>

A student of mine says that when he sails off the Washington coast the
maps he uses show a 5 degree offset from true north. Textbooks I've
consulted, however, show that the declination is closer to 20 degrees.
Can anyone resolve this?

Thanks,
