Azimuth and Bearing: I know I've explained this before. Go back a few pages on this thread.

Build-a-map: Very simple, just have a map symbols sheet, a protractor, and a ruler. Know how to read PLSS. It's really very self explanatory.

Magnetic Declination: I'm working on it.

Sorry for the double post, here's what I got:
The magnetic declination in a given area will change slowly over time, possibly as much as 2-2.5 degrees every hundred years or so, depending upon how far from the magnetic poles it is. This may be insignificant to most travellers, but can be important if using magnetic bearings from old charts or metes (directions) in old deeds for locating places with any precision.

Do your best and use common sense, you'll probably be able to figure it out using the index contours.
