Reading sections near Hannibal
For land around Palmyra, numbering starts with section 1 in the northeast corner, with the count snaking back and forth to 36 in the southeast. Quarter-quarter descriptions in Marion County are read from the end: locate the southwest quarter, then its northeast quarter, on the Marion County grid. Correction lines and irregular sections exist, so a section near Palmyra may not be exactly 640 acres.
