The Story
This stone marks the base point established on November 10, 1815, from which U.S. surveyors laid out the vast lands of the Louisiana Purchase using the Fifth Principal Meridian. One of the first surveys from this point served to satisfy the land-bounty claims of soldiers who had fought in the War of 1812. From this humble marker in the Arkansas wilderness, the grid that organized much of the American interior was reckoned.
Why it matters
It is the literal starting point for surveying an enormous share of the American heartland, anchoring the orderly settlement of the trans-Mississippi frontier.
The story behind this marker
AI contextThe era
In the years after 1803, the young United States suddenly owned an interior it had barely seen. The Louisiana Purchase roughly doubled the nation's size, sweeping in a vast expanse of prairie, river bottom, and forest west of the Mississippi. On paper it belonged to the government; in practice it was a blank space that needed to be measured, mapped, and divided before it could be sold or settled in an orderly way.
By 1815 the country was emerging from the War of 1812 and turning its attention back toward that western land. This corner of what is now Phillips County, Arkansas, sat deep in swampy, hard-to-reach bottomland near the Mississippi and its tributaries — not a place anyone would build a city, but a fixed, defensible point from which a survey could begin.
The federal government's answer to the problem of dividing an empire was the rectangular survey system: a grid of townships and ranges reckoned outward from carefully chosen baselines and meridians. This stone marks one of those origins, the base established here in November 1815, from which the Fifth Principal Meridian would be run.
People & events
The work here was done by United States surveyors and engineers, the anonymous professionals who walked the wilderness with chains and compasses so that clerks in distant land offices could sell parcels no one had yet trodden. From this initial point they laid out a principal meridian running north and a baseline running east and west, the two reference lines that every later measurement in the region would hang upon.
One of the first tasks that pushed surveyors into this ground was the promise the nation had made to its soldiers. Veterans of the War of 1812 had been offered land bounties — grants of acreage in exchange for their service — and those claims could not be honored until the land itself was measured into townships and sections. The early survey from this point was undertaken in part to make good on that promise.
There is a quiet human drama in that. A stone driven into an Arkansas swamp connected a farmer-soldier who had shouldered a musket to a specific rectangle of earth he might one day own. The inscription records the beginning of that reckoning, the moment the abstract idea of "bounty land" started to become real acres with real corners.
Its place in the American story
It is hard to overstate how much of the American map traces back to points like this one. The Fifth Principal Meridian and its baseline became the framework for surveying an enormous share of the country's interior — the ordered checkerboard of square fields, mile-straight roads, and right-angled county lines that travelers still see from an airplane window across much of the heartland.
That grid was more than geometry. It was the machinery that turned newly acquired territory into salable, settleable, governable land, allowing the United States to distribute the trans-Mississippi frontier in an orderly way rather than through pure chaos and squatting. The rectangular survey shaped how towns were platted, how farms were sized, and how ownership was recorded for generations.
So a modest stone in a remote county quietly anchors a continental project. From this humble base, the lines were run that helped organize the settlement of a huge portion of the American interior — one of those small, unglamorous origin points on which a great deal of the nation's physical shape depends.
If you visit
Come expecting something understated. This is a marker about a beginning, not a battlefield or a grand monument, and its power is in what it represents rather than in spectacle. The setting is low, wooded Arkansas bottomland, and part of the experience is simply grasping that so much order radiated outward from so quiet a spot.
Stand for a moment and think in lines. Somewhere from this point a meridian was run true north and a baseline east and west, and from those two strokes came the townships and sections that organized a vast stretch of country. If you have ever driven long, arrow-straight rural roads that turn at perfect right angles, you have felt the descendants of the work begun here.
It makes a fine, offbeat stop for anyone drawn to the hidden scaffolding of American history — the kind of place that rewards curiosity over sightseeing. Bring your imagination, respect the surroundings, and let the sheer reach of that first survey do the rest.

Pierre Laclede Liguest
Arkansas County, AR
This monument commemorates Pierre Laclède Liguest (1729–1778), the French fur trader and merchant who founded St. Louis in 1764 near the confluence of the Mississippi and Missouri rivers. Laclède died in 1778 near Arkansas Post, the early French and Spanish colonial outpost on the lower Mississippi where this marker stands. His trading venture helped plant one of the great gateway cities of the American interior.
Benjamin Crowley Monument
Greene County, AR
Crowley's Ridge is a long, narrow upland winding through the flat lowlands of eastern Arkansas, and this monument honors the settler whose name it carries. Benjamin Crowley (1758–1842) came west in the early 1800s to help pioneer this corner of the Arkansas country, joining the first wave of Anglo-American families to put down roots on the ridge. His name has stuck to the landform ever since.
Tennessee Historical Marker 4D 36
Crockett County, TN
This marker points the way to the grave of a Revolutionary War soldier who joined the Continental cause in 1776 and endured the brutal winter encampment at Valley Forge, where Washington's ragged army drilled itself into a disciplined fighting force. After years of battle he turned west, fighting in the frontier campaigns against Native nations before receiving an honorable discharge at Pittsburgh — then the raw edge of American settlement at Fort Pitt. Like many aging veterans, he eventually followed the frontier south and west, coming to rest in the West Tennessee country that became Crockett County.
Parley P. Pratt Memorial and Gravesite
Crawford County, AR
Parley P. Pratt was one of the original Twelve Apostles of the young Latter-day Saint church, a prolific author and missionary whose writings helped shape early Mormon thought. Born in upstate New York in 1802, he spent his life on the move as the faith pushed westward, and he met a violent end near Alma, Arkansas, in 1857. This memorial marks his grave far from the Mormon settlements of the Great Basin.
