Locating features Using the United states Public soil Survey system (Township and Range) and Google EarthTM

Section: The basic unit that the system, a square item of land one mile by one mile include 640 acres.

You are watching: How many acres are in a quarter section of land

Township: 36 sections i ordered it in a 6 by 6 square, measure 6 miles by 6 miles. Sections are numbered beginning with the northeast-most section (#1), proceeding west to 6, then southern along the west leaf of the township and to the eastern (#36 is in the SE corner).
Range: Assigned to a township by measuring eastern or west the a primary Meridian
Range Lines: The phibìc to south lines which mark township boundaries.
Township Lines: The eastern to west lines which note township boundaries.
Principal Meridian: The referral or beginning allude for measuring eastern or west ranges. Map of meridians & basic lines native the BLM net server
Base line: reference or beginning allude for measuring phibìc or southern townships.

Understanding floor Descriptions We"ll begin with the largest grouping, the township. The location of a particular township is given using the terminology of "township and also range". The township is called in referral to a primary Meridian and a Baseline. Here is an example, T.2N., R.1E. The T.2N. Refers to Township 2 north (of the Baseline), and the R.1E. Refers to selection 1 eastern (of the major Meridian).

Next, each township is separated into 36 sections. Each section is one mile square and contains 640 acres. The sections room numbered indigenous 1 to 36 in the order shown in the graph to the left (see the yellow squares which display a "complete" township). The various other colored squares represent "incomplete" townships.

Within each section, the floor is referred to as half and 4 minutes 1 sections. A one-sixteenth division is referred to as a quarter of a quarter, together in the NW1/4 of the NW1/4. The descriptions are review from the smallest department to the largest.


ONE section = 640 acre

A section is likewise broken down into acres. Sample descriptions room in the ( )s.
A complete section includes 640 Acres.
A fifty percent section (S1/2) contains 320 Acres.
A quarter section (NE1/4) includes 160 Acres.
An eighth section (N1/2 that NW1/4) contains 80 Acres.
A sixteen section (SW1/4 that NW1/4) contains 40 Acres.
Locating a place Using USPLS floor Descriptions A land summary generally starts with the smallest part of the description and also proceeds come the biggest definition. Because that example, NW1/4 of NE1/4 of section 8, T.2N., R.1E. Would certainly be the northwest 4 minutes 1 of the northeast 4 minutes 1 of section 8 in township 3 phibìc and range 2 east. To locate a function on the landscape utilizing a floor description, you have to work native the largest component to the the smallest part.


Step 1
As stated above, to locate a attribute of interest, girlfriend should situate the largest component using the township and selection supplied in the summary first. In this case T.2N., R.1E. Mental the T.2N. Refers to Township 2 phibìc (of the Baseline), and the R.1E. Advert to range 1 eastern (of the principal Meridian).
Step 2 ~ you have located the correct township, you will next require to discover the correct ar within that township. Using the example given above the land description states section 8, T.2N., R.1E. For this reason you would look in the township discovered in step 1 for section 8.


Step 3 now that you have actually located the correct ar you need to discover where in this section your land attribute is located. Our example says NW1/4 that NE1/4 of section 8, T.2N., R.1E. So you would first look in ar 8 for the NE1/4 of the section (shown together orange in the graph to the left.) after ~ locating the NE1/4 the the section your last action will it is in to discover the NW1/4 of that NE1/4 (shown in aqua in the graph to the left.) The well is usually located at or near the center of the critical unit given.

Let"s look at at an example using Google EarthTM in Arizona

The image listed below shows the townships neighboring the intersection of the major Meridian and the Baseline (the township with Avondale and Tolleson plus the two straight south the them) in the State that Arizona. The theseTownships, the ones labeling T. 1 N. Are in a position one township north of Baseline (which is Baseline Road) and those labeled T. 1 S. Space one township to the south. Variety values labeled with a "W" space one township west of the principal Meridian and those through an "E" are one come the east. I have actually also marked the facility of township T. 1 S., R. 2 W. (one township southern of Baseline and two townships west of the primary Meridian). We will certainly zoom in on the township containing Tolleson in the next picture below.


Next we view the township T. 1 N., R. 1 E. In addition to the 36 sections that makeup the township itself. Note the numbering system. Section 1 is in the extreme NE corner of the township and we number them moving west. Drop down a row and continue numbering moving east. Keep numbering in this fashion till we with the last section, number 36, discovered in the too much SE edge of the township. In one exercise, you room asked to determine if over there are any kind of "complete" congressional townships. To identify this, you should see every 36 part in their totality for the whole township numbered as displayed below. If any component of a ar or sections is missing, then the township is not complete.

Now, let"s look at the Glendale Quadrangle v the township overlays displayed. The orange borders are the outlines that the townships and the purple borders are the outlines because that the individual sections. Space there any kind of complete townships ~ above the Glendale Quadrangle? Look in ~ it prior to you check out the answer...No, there aren"t any type of complete townships. How countless incomplete townships space there? counting them before you review the answer...There are four incomplete townships on the Glendale map. As soon as you should do this top top the Folsom, NM quadrangle, you will have to survey (carefully look over) the map and determine if over there is a complete township top top the map. Given the dimension of a township loved one to a 1:24,000 map (scale the Folsom, NM quad is the same as the for Glendale below), that is unlikely that there would be more than one complete congressional township top top the map area. Once you"ve excellent that, you need to count how numerous incomplete townships there are. Be careful that you execute not count the sections. Township T. 3 N., R. 1 E. Is highlighed with a thicker orange synopsis (upper left township). Any kind of object of attention (school, house, business, etc) inside this box would have a USPLS designation that T. 3 N., R. 1 E. The City that Glendale would be in T. 2 N., R. 2 E. To see the divisions in between the townships, we have to zoom in come the edge of the map area and also look because that the red text. The image below this big map mirrors an enlargement of together a division along the top edge the the map (where the orange township boundary intersects the map edge). See below where the orange line separates R. 1 E. Native R. 2 E.
