The General Land Office ( GLO ) was an independent agency of the United States government responsible for public domain lands in the United States. It was created in 1812 to take over functions previously conducted by the United States Department of the Treasury . Starting with the enactment of the Land Ordinance of 1785 , which created the Public Land Survey System , the Treasury Department had already overseen the survey of the Northwest Territory , including what is now the state of Ohio.
57-716: The Logan Forest Reserve was established by the United States General Land Office in Utah on May 29, 1903 with 182,080 acres (736.9 km). In 1905 federal forests were transferred to the U.S. Forest Service . On May 28, 1906 the forest was combined with other lands to establish Bear River Forest Reserve and the name was discontinued. The lands are presently included in Uinta-Wasatch-Cache National Forest . United States General Land Office Placed under
114-408: A 10-mile (16 km) range of one square mile sections was allotted on each side of the 400-foot (120 m) right-of-way. If the railway ran predominantly north and south, a 10-mile (16 km) township of one square mile sections was allotted on each side of the 400-foot (120 m) right-of-way. The land was granted in alternating sections (one square mile), with each odd numbered section going to
171-415: A railroad right-of-way to build rail systems, and millions of acres to raise the capital needed to build and maintain the future railways. Ten square miles of land on each side of the proposed rail track were granted for every one mile of completed railway. The PLSS was utilized for measurement. Every one-mile length of railway completed was akin to a section. If the railway ran predominantly east and west,
228-629: A single Willamette Meridian serves both Oregon and Washington . County lines frequently follow the survey, so there are many rectangular counties in the Midwest and the West . The system is in use in some capacity in most of the country, but large portions use other systems. The territory under the jurisdiction of the Thirteen Colonies at the time of independence did not adopt the PLSS, with
285-479: A state or multiple states, is a multi-step process. First, two controlling survey lines are established: a baseline which runs east–west and a principal meridian which runs north–south. The locations of the two are determined by a previously chosen initial point , where they originate and thus intersect. Next, at a defined distance interval, commonly 24 or 30 miles (48 km) depending on the year and location, standard parallels of latitude are established parallel to
342-633: A town of a generally rectangular shape, 4 to 6 miles (6.4 to 9.7 km) on a side. Within this boundary, a map or plat was maintained that showed all the individual lots or properties. There are some difficulties with this system: In the 1783 Treaty of Paris recognizing the United States, Britain also recognized American rights to the land south of the Great Lakes and west to the Mississippi River . The Continental Congress passed
399-439: A township line (or baseline) with a range line (or principal meridian) constitutes a township corner , of a section line with any other type of line a section corner , and a point halfway between any two section corners a quarter corner . The federal government typically surveyed only to this quarter-section level, the subdivision of smaller parcels being carried out subsequently by private surveyors after original sale. Because
456-716: A way of raising money for the nation. Before this could happen, the land needed to be surveyed. The Land Ordinance of 1785 marks the beginning of the Public Land Survey System. The Confederation Congress was deeply in debt following the Declaration of Independence . With little power to tax, the federal government decided to use the sale of the Western Territories to pay off war debt. The PLSS has been expanded and slightly modified by Letters of Instruction and Manuals of Instruction, issued by
513-457: Is always used, in which the townships and sections are indexed based on (1) the township's position relative to the initial point, (2) the section's location within the designated township, and (3) the principal meridian reference. Township, range, and section are abbreviated as T, R, and S, respectively, and cardinal bearings from the initial point by N, S, E, and W; each principal meridian also has its established abbreviation. Thus, for example,
570-788: Is the surveying method developed and used in the United States to plat , or divide, real property for sale and settling. Also known as the Rectangular Survey System, it was created by the Land Ordinance of 1785 to survey land ceded to the United States by the Treaty of Paris in 1783, following the end of the American Revolution . Beginning with the Seven Ranges in present-day Ohio ,
627-552: Is the one at lowest elevation, i.e. in the direction that water drains. The "lower 40" is frequently the location of or the direction of a stream or a pond. The phrase "40 acres and a mule" was the compensation apocryphally promised by the Freedmen's Bureau following the American Civil War . Homesteading , a staple of American western culture , was dependent on the PLSS. In the original Homestead Act of 1862, during

The GLO oversaw the surveying , platting , and sale of the public lands in the Western United States and administered the Homestead Act and the Preemption Act in disposal of public lands. The frantic pace of public land sales in

Section 36 was also subsequently added as a school section in western states. The various states and counties ignored, altered or amended this provision in their own ways, but the general (intended) effect was a guarantee that local schools would have an income and that
798-584: The 19th century American West led to the idiomatic expression "land-office business", meaning a thriving or high-volume trade. For most of the active period of public land settlement, district land offices were the basic operating units that conducted the business of transferring title. All transactions relative to the disposal of public land within a declared land district were handled through its land office by officials designated as registers , who recorded land applications, and receivers , who accepted payments for land and issued receipts. The position of receiver

These public land surveyed had no initial point as an origin for both township and range. The Pacific Railroad Act of 1862 (signed by President Abraham Lincoln ) was the first major land grant specifically for the transcontinental railroad . This act provided surveyed, public lands for
912-715: The GLO gained a focus for conservation of renewable public resources, as well as for their exploitation. On July 16, 1946, the GLO was merged with the United States Grazing Service (established in 1934 under the Taylor Grazing Act ) to become the Bureau of Land Management (BLM), an agency of the Interior Department responsible for administering the remaining 264,000,000 acres (1,070,000 km ) of public lands still in federal ownership. An early commissioner

The original colonies (including their derivatives Maine , Vermont , Tennessee , Kentucky and West Virginia ) continued the British system of metes and bounds . This system describes property lines based on local markers and bounds drawn by humans, often based on topography. A typical, yet simple, description under this system might read "From
1026-649: The Land Ordinance of 1785 and then the Northwest Ordinance in 1787 to control the survey, sale, and settling of the new lands. The original 13 colonies donated their western lands to the new union, for the purpose of giving land for new states. These include the lands that formed the Northwest Territory, Kentucky, Tennessee, Alabama , and Mississippi . The state that gave up the most was Virginia , whose original claim included most of
1083-527: The Northwest Territory and Kentucky. Some of the western land was claimed by more than one state, especially in the northwest, where parts were claimed by Virginia, Pennsylvania, and Connecticut , all three of which had claimed lands all the way to the Pacific Ocean. The first surveys under the new rectangular system were in eastern Ohio in an area called the Seven Ranges. The Beginning Point of
1140-464: The PLSS grid structure. The results can be 90-degree intersections and very long stretches of straight roads. The land system is an important part of American history and culture. Among other things, the stock phrases "lower 40", "front 40", "back 40", and " 40 acres and a mule ", which are sometimes heard in American movies , reference the quarter-quarter section. The "lower 40" in a quarter-section
1197-614: The PLSS has been used as the primary survey method in the United States. Following the passage of the Northwest Ordinance in 1787, the Surveyor General of the Northwest Territory platted lands in the Northwest Territory . The Surveyor General was later merged with the United States General Land Office , which later became a part of the U.S. Bureau of Land Management (BLM). Today, the BLM controls
SECTION 20
#17328009488181254-676: The U.S. Public Land Survey is at a point on the Ohio-Pennsylvania border between East Liverpool, Ohio , and Ohioville, Pennsylvania , on private property. A National Historic Landmark marker commemorating the site lies on the side of a state highway, exactly 1,112 feet (339 m) to the north of the point. Ohio was surveyed in several major subdivisions, collectively described as the Ohio Lands , each with its own meridian and baseline . The early surveying, particularly in Ohio,
1311-699: The baseline. The meridian, baseline and standard parallels thus established form a lattice upon which all further surveying is then based. Subsequent work divides the land into survey townships of roughly 36 square miles (93 km ) or 6 miles (9.7 km) on each side. This is done by the establishment of township and range lines. Township lines run parallel to the baseline (east-west), while range lines run north–south; each are established at 6-mile intervals. Lastly, townships are subdivided into 36 sections of approximately 1 square mile (640 acres; 2.6 km ) and sections into four quarter-sections of 0.25 square miles (160 acres; 0.65 km ) each. The intersection of
1368-424: The community schoolhouses would be centrally located for all children. An example of land allotments made specifically for higher education is Ohio's College Township . There were numerous incidents of fraudulent or bad surveying reported, arguably in nearly every state. The remote nature of the land being surveyed certainly enabled the opportunity for fraud to occur. The most notorious, large scale, and costly fraud
1425-568: The description "T1SR20E S13 MDM" reads as follows: Township 1 South, Range 20 East, Section 13, Mount Diablo Meridian. That is, the 13th section in the first township south of the baseline (in this case, the Mount Diablo Baseline) and the 20th township east of the principal meridian (the Mount Diablo Meridian). Since township and range lines are six miles apart, the "T1SR20E" part of the designation instantly places
1482-448: The estimation of historic forest vegetation conditions before settlement and large scale human disturbance of the land. The data provided in these surveys provide a definitive estimate of original forest composition and structure, and the data have accordingly been used heavily. Along survey lines, monumentation was much less elaborate, consisting primarily of only the blazing and some simple scribing of trees directly on, or very close to,
1539-473: The exception of the area that became the Northwest Territory and some of the southern states . This territory comprises Georgia , Connecticut , Delaware , Kentucky , Maine , Maryland , Massachusetts , New Hampshire , New Jersey , New York , North Carolina , Pennsylvania , Rhode Island , South Carolina , Tennessee , Vermont , Virginia , and West Virginia . The old Cherokee lands in Georgia use
1596-454: The ground. As with most PLSS specifications, those for corner monumentation also changed over time. In the 19th century, monuments were commonly a rock pile, a wooden post, or a combination of the two. Trees could be used if the corner happened to fall at the exact spot where one grew. In the 20th century, steel pipes with caps, supported by mounds of rock, became required (for example, see Fig. 4). Witnesses can be trees, rocks, or trenches dug in
1653-488: The ground; their exact locations relative to the corner, and the markings made on them, are also recorded in the surveyor's official fieldnotes . Witness trees at corners are more commonly referred to as bearing trees because the exact distance and bearing from the corner, to them, was required to be recorded (as well as the taxon and diameter). On each bearing tree, two blazes were typically required, one about chest height and easily visible, and one at ground level (in case
1710-434: The lead chainman follow the correct bearing at all times, since no straightening of the chain was possible without backtracking around trees and re-measuring. It was also necessary to keep the chain level, since all surveying distances are based on the horizontal, not slope, distance. In steep terrain, this meant shortening the chain, raising one end of the chain relative to the other, or both. In areas where measuring by chain
1767-623: The location somewhere between zero and six miles south of the baseline, and 114 and 120 miles east of the principal meridian. Knowing how sections are numbered within townships, section 13 is identified as therefore occupying the one square mile located 2 to 3 miles south, and 119 to 120 miles east, of the Mount Diablo initial point (in central California). Note that the sections within a township are numbered in an unconventional, Boustrophedon pattern (Fig. 2), in which alternating rows are numbered in opposite directions, starting from section 1 in

1824-492: The newly created Forest Service , under the Department of Agriculture . Beginning in the early 20th century, the GLO shifted from a primary function of land sales to issuing leases and collecting grazing fees for livestock raised on public lands, and royalties from minerals off lands recently withdrawn from disposal under the Withdrawal Act of 1910, as well as other custodial duties. Thus, beginning around 1900,
1881-474: The northeast corner and ending with section 36 in the southeast corner, as per Figure 2. Therefore, section 13 is adjacent to the eastern range line of the designated township. Numbering in this pattern ensures that numerically sequential sections within the same township are physically adjacent and share colinear boundaries. Distances were always measured in chains and links, based on Edmund Gunter 's 66-foot measuring chain . The chain – an actual metal chain –

1995-440: The original corner monument location should the monument be destroyed. It was not uncommon for squatters or homesteaders to destroy corner monuments if they felt the patenting of the land would threaten their residence on it. For this reason, destruction of corner monuments, or their accompanying witness objects was, and still is, a federal offense. At corners, corner monuments are established to mark their exact location on
2052-403: The other (southeasterly-most) 25 sections are not. This method accommodates the curvature problem within a township and also allows for any errors made during the surveying—which were nearly unavoidable because of the physical difficulty of the work and the crude equipment used—without overly compromising the basic rectangular nature of the system as a whole. At the larger multiple township scale,
2109-466: The point on the north bank of Muddy Creek one mile above the junction of Muddy and Indian Creeks, north for 400 yards, then northwest to the large standing rock, west to the large oak tree, south to Muddy Creek, then down the center of the creek to the starting point." Particularly in New England , this system was supplemented by drawing town plats . The metes and bounds system was used to describe
2166-400: The prime meridian, are always established with reference to true, geodetic north. But it is a physical impossibility to meet this condition and still maintain a rectangular land grid, because such lines converge on the north pole. These adjustments are done at two different scales. At the small scale (within a township) it is done by starting the sectional surveys (township "subdivisions") in
2223-429: The railroad company and each even numbered section kept by the government. This created a checkerboard pattern along proposed railways. This was supposed to guarantee that railroad access would increase the value of both the railroad-granted sections and the government-owned sections in the checkerboard. The system was devised by Senator Stephen A. Douglas , with political support from Senator Jefferson Davis . Under
2280-520: The rest of the former square-mile sections have generally filled with residential development, as well as schools, religious facilities, and parks. One example of this is the Mile Road System of Detroit, Michigan . Occasionally, and more frequently in a metropolitan region's inner postwar suburbs than in outer areas, arterials are at approximately half-mile intervals. This strictly regimented urban (or suburban) structure has coincided with
2337-503: The similarly strict practice of Euclidean zoning (named after the town of Euclid, Ohio , which won a 1926 Supreme Court case Village of Euclid, Ohio v. Ambler Realty Co. , which established the constitutionality of zoning). In Euclidean zoning, use of a property is dictated and regulated by zoning district, the boundaries of which are often based on locations of arterials. West of the Appalachians , road systems frequently follow

2394-487: The southeast corner and moving progressively toward the northwest corner. The algorithm used is to move northward to establish the six easternmost sections (and quarter-sections), then move west at one mile intervals, parallel to the eastern boundary of the township, repeating this process, until the western side of the township is reached. The result of this is that the northernmost and westernmost tiers of sections—11 in all—are thus allowed to deviate from one square mile, but
2451-501: The standard parallels developed at the establishment of the baseline, so that townships widths do not continually decrease as the grid proceeds north (and is in fact the primary reason for their establishment). Thus, corrections for curvature of the Earth exist at two separate spatial scales—a smaller scale within townships and a larger scale between multiple townships and within standard parallels. A specific and terse location descriptor
2508-421: The survey design is two-dimensional (rectangular), while the actual Earth is three-dimensional (approximately spherical and topographically), adjustments to land areas must be made periodically to prevent error propagation; not all sections can be one square mile nor can all townships be exactly 36 square miles. More specifically, all north–south running lines (all range lines and half of all section lines), as with
2565-413: The survey line. The purpose was to help retrace a surveyed line should that become necessary. It was also additional proof that the line had in fact been run correctly, especially in those cases where the blazed line tree's pertinent information (species, diameter and distance from previous corner) was recorded in the fieldnotes, as was often required. Records kept by the surveyors during the execution of
2622-535: The survey, sale, and settling of lands acquired by the United States. Originally proposed by Thomas Jefferson to create a nation of " yeoman farmers", the PLSS began shortly after the American Revolutionary War , when the federal government became responsible for large areas of land west of the original thirteen states . The government wished both to distribute land to Revolutionary War soldiers in reward for their services and to sell land as
2679-449: The term section as a land designation, but it does not define the same area as the section used by the PLSS. Maine uses a variant of the system in unsettled parts of the state. Parts of Texas, western New York, northwest Pennsylvania, western Georgia, western Kentucky, western Tennessee, and northern Maine use state-developed survey systems similar to PLSS. Other major exceptions to PLSS are: The surveying of any regional area, such as
2736-498: The tree were illegally cut, the stump remaining). On the exposed wood of the blaze, surveyors were required to inscribe, with wood chisels, township, range and section information, on typically either two or four bearing trees, if they were within some reasonable distance of the corner (unspecified early on but later set at a maximum of 3 chains (178 feet, 60 meters) away). Bearing trees are of vital importance not just for these land boundary purposes but also for their use by ecologists in
2793-476: The work varied over time. Furthermore, how well individual surveying parties actually met the requirements or recommendations at the time, also varied. The following is a list of the more commonly required landscape and surveying items that were either required or requested be noted, over much of the nineteenth century. The following table indicates some distance and area conversions in the PLSS: Based on

The BLM makes images of GLO records (federal land patents, survey plats and field notes, land status records, and tract books) issued between 1787 and present publicly available on its website. Since 1990, the BLM's Geographic Coordinates Database (GCDB) program has endeavored to generate coordinate values for each established PLSS corner using

The first of 362 district land offices was opened at Steubenville, Ohio , on July 2, 1800; the last at Newcastle, Wyoming , on March 1, 1920. The peak year for land offices was 1890, with 123 in operation. The subsequent closing of the public domain gradually reduced the number of land offices, until, in 1933, only 25 offices remained. The GLO
SECTION 50
#17328009488182964-1202: Was adopted without issue. "...the measurements of every plot of ground in the United States have been made in acres, feet, and inches, and are publicly recorded with the titles to the land according to the record system peculiar to this country." —Franklin Institute of Philadelphia (1876). Because of this, redefining property boundaries could create a large amount of legal issues and property owner confusion. Many local zoning laws are defined in feet/square feet. Conversion of units for surveyors are not simple, and complex decisions are frequently required (such as non-universal conversion factors, soft/hard conversions, number rounding). As roads have typically been laid out along section boundaries spaced one mile (1.6 km) apart, growing urban areas have adopted road grids with mile-long "blocks" as their primary street network. Such roads in urban areas are known as section line roads , usually designed primarily for automobile travel and limited in their use for non-motorized travel. In post- World War II suburbs, commercial development has largely occurred along and at intersections of arterials , while
3021-443: Was made up of 100 links, each being 7.92 inches (201 mm) long. Eighty chains constitute one U.S. survey mile (which differs from the international mile by a few millimeters). There were two chainmen, one at each end, who physically made the measurements, one of them typically also acting as "compassman" to establish the correct bearing at each chain placement. In forested areas, it was essential for rapid progress and accuracy that
3078-532: Was not possible, such as extremely steep terrain or water obstructions, distances were calculated by triangulation . Monumentation is the establishment of permanent on-the-ground objects that mark exact locations of surveyed points and lines. They are the legally binding markers used for setting property lines and as such are the culminating work of any survey. They consist of both corner monuments as well as nearby accessory objects that "witness" to them. Witness objects allow subsequent surveyors and landowners to find
3135-431: Was performed with more speed than care, with the result that many of the oldest townships and sections vary considerably from their prescribed shape and area. Proceeding westward, accuracy became more of a consideration than rapid sale, and the system was simplified by establishing one major north–south line ( principal meridian ) and one east–west (base) line that control descriptions for an entire state or more. For example,
3192-578: Was perpetrated by the Benson Syndicate , operating primarily in California in the 1880s. The PLSS is considered one of the major points of contention in the adoption of the metric system in the United States . The PLSS has used the Gunter's chain as a basic measurement. In Canada, however, where the land survey is based on the same units of measure as the U.S. land survey, the metric system
3249-619: Was placed under the Secretary of the Interior when the Department of the Interior was formed in 1849. Reacting to public concerns about forest conservation, Congress in 1891 authorized the President to withdraw timber lands from disposal. Grover Cleveland then created 17 forest reserves of nearly 18,000,000 acres (73,000 km ), which were initially managed by the GLO. In 1905, Congress transferred responsibility for these reserves to
