Sections, quarters and roads in Lee County
Near Ashton, sections are numbered from 1 in the northeast corner, with the count snaking back and forth to 36 in the southeast. Calls like 'NE 1/4 of the SW 1/4' near Ashton make sense in reverse: locate the southwest quarter, then its northeast quarter, on the county grid. Correction lines and irregular sections exist, so a section near Harmon may not be exactly 640 acres.

Older deeds near Harmon may name a township differently than today's Lee County records, so compare the legal description too. For property tax questions, the township shown on the county record for a parcel near Harmon is the one that counts.
