Each Township-and-Range square, called a “township” for short, is usually (but not always) 6 miles on a side and contains 36 square “sections.” Sections are numbered from the northeast corner by “boustrophedon,” (boos-truh-FEED-un) a two-dollar word that means “as the ox plows.” Section 22 is almost in the middle.


One section = 1 square mile = 640 acres. Townships vary but sections are constant. Sections are further divided into halves, quarters, halves of quarters (eighths) and so on. The “west half of the north east quarter” defines an 80-acre tract, 1/4 mile east-to-west by 1/2 mile north-to-south.

How can I determine what the section number is?
Each section number is clearly marked on the township page in the center of each section (see illustration below).

What are tier and range numbers?
These numbers represent Township and Range and are indicated at the top of each Township page (see illustration below).

Most townships have one section that was donated to the school.Usually dead center in the 36 section parcels. Many of these are no longer a school,but actually the site of a former one.....these are a great place to find and search.

I can help in any other questions about Plat Maps, Sections or Metes and Bounds

I am a surveyor and I can try to answer questions you might have on most any kind of Plat Maps. (It's what I do for a living).

Good info Gyps!

I use plat maps extensively when I research. I have a current copy that I buy from the bank, and then I bounce it against several older plats of the same area at the library. What I like best about them is that the "SE quarter of the SW quarter of Section 22 of Gutrot Township" in 1880 is STILL the "SE quarter of the SW quarter of Section 22 of Gutrot Township" in 2008, as an example. I also use them in conjunction with current topo maps and the Microsoft Live! Map Server I find them especially helpful in locating old school, homestead, and ghost town sites. I'm ALWAYS doing research! Even right now in Iraq as I write this post I am downloading topo maps of the counties that I hunt in Michigan that I found on the Michigan DNR's website. 43 more days and I'm OUTTA here for home!

i worked for a surveyor every summer starting when i was 12 and then went to work full time after graduation.....wish i MD back then...ran across SEVERAL old homesites deep in the woods......but that was about 18 years ago...but i do have a question.....we would plot off the spot we were working using a description....im sure you know what i am saying....what i want to know is..are there any kind of software that would do this for you?....I'm looking into buying tax siezed properties and if i could get the location i could go and see the property before i decide if i want it or not.....it would also help in our hobby if we had some kind of program for this.
