Wikipedia wrote: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.

For instance, if there is an orchard in the northwest corner of section 30, then you write NW 1/4 NW 1/4 30 to start. Then, you have to write T # S R # W, which indicates township and range, and can be found in quadrangle margins. So in all a PLSS description could look like: "NW 1/4 NW 1/4 30 T12S R7W" For more information, read the Wiki. You can find stuff about sectors there too.
