Townships organize a lot of rural life near Monticello, from road upkeep to how land is described, and a Jones County township map shows their lines. Here's how to see township lines for Jones County, Iowa, on free official maps.
What a Jones County township map shows
Where civil townships exist in the county, they are named local units, and their duties near Olin depend on Iowa law. The survey township cited in deeds near Onslow follows the federal survey grid, where a licensed survey township is about 6 miles square, split into 36 sections of about 640 acres.
