Tridens Prairie
Brookston, Lamar County, Texas
Marker Inscription
In 1841, when Zacharia Westfall was granted 1280 acres of land in this area, much of the northeastern region of Texas was covered with natural prairies. Over the years most of them have been plowed or destroyed. Tridens Prairie, which covers 97 acres of Westfall's original grant, is an undisturbed remnant of the blackland prairie that now is under preservation management. Tridens Prairie is part of a natural grassland that extends from Texas through the midwestern United States and into southern Canada. Its name is derived from the native, perennial bunch grass known as Long-spiked tridens. Over 150 species of grasses and wildflowers have been identified in Tridens Prairie. Dominant grasses of the prairie include Sporobolus silveanus (Silveanus dropseed), Tridens strictus (Long-spiked tridens), Paspalum floridanum (Florida paspalum), and Tripsacum dactyloides (Eastern gama). One of the few remaining native grasslands in the state and once part of a large hay-producing region, Tridens Prairie is an important part of Texas' natural history. It is being preserved by the Texas Nature Conservancy and Texas Garden Clubs, Inc. (1985)

The Story
When Zacharia Westfall received his 1,280-acre land grant here in 1841, the blackland prairies of northeastern Texas stretched unbroken toward the horizon. Within a few generations the plow had erased nearly all of them. Tridens Prairie—97 acres of Westfall's original grant left undisturbed—survives as a rare window onto the tallgrass grassland that once ran from Texas up through the Midwest and into Canada, home to more than 150 species of native grasses and wildflowers.
Why it matters
This remnant preserves a vanishing American landscape, reminding visitors that the settlement and cultivation that transformed the frontier also swept away an ancient prairie ecosystem now almost entirely gone.
The story behind this marker
AI contextThe era
Picture northeastern Texas in 1841. This was the era of the Republic of Texas, a young and independent nation still finding its footing between Mexico and the United States, actively drawing settlers onto its land. When Zacharia Westfall received a grant of 1,280 acres in this area, he was stepping into a landscape that would astonish anyone raised in the wooded East: a rolling sea of grass stretching to the horizon.
These were the blackland prairies, named for the dark, sticky, fertile soil beneath them. To a farmer's eye that black earth was a promise, and over the following generations that promise was kept — the prairies were plowed under, fence line by fence line, and turned into cropland and pasture. What had looked endless proved fragile. An ecosystem that took thousands of years to form could be undone in a single season behind a plow.
Tridens Prairie is what remains when almost everything else has been converted. Ninety-seven acres of Westfall's original grant were never broken, and that accident of history left behind a living remnant of the grassland that once ran unbroken from Texas up through the American Midwest and into southern Canada.
People & events
The human story here is deceptively quiet. Zacharia Westfall's name survives on this marker not because of a battle or a famous deed, but because his land grant is the thread that ties this patch of ground to the frontier era. In 1841 a grant like his was an invitation to build a life on the edge of a new republic, and countless settlers answered similar invitations across northeastern Texas.
What makes this place unusual is what did not happen to it. Most of Westfall's acreage, and the vast prairie surrounding it, followed the ordinary path of settlement: the grass was cut for hay, the sod was turned, the land was put to work. This region was once a major hay-producing area, and that alone tells you how completely the prairie was seen as a resource rather than a wonder.
But these 97 acres were left undisturbed, and in that stillness a different kind of history was preserved. More than 150 species of native grasses and wildflowers have been identified here — among them the long-spiked tridens bunchgrass that gives the prairie its name, along with Silveanus dropseed, Florida paspalum, and eastern gama grass. Each is a survivor of a community that once covered a huge share of the continent, and their presence together is the real event this marker commemorates.
Its place in the American story
The story of Tridens Prairie is, in miniature, the story of the American grassland itself. The tallgrass and mixed prairies that once blanketed the heart of the continent — from Texas through the Midwest and into Canada — were among the richest ecosystems in North America and also among the most thoroughly erased. The same fertility that sustained the grass made the land irresistible to the plow.
That is the larger meaning of settlement and westward expansion that a place like this quietly complicates. The transformation of the frontier into farmland was a genuine achievement, but it came at a cost that was invisible at the time and is only fully legible now, when so little original prairie is left that a 97-acre remnant becomes a treasure. Native grasslands are today among the rarest landscapes in Texas.
Preserving a fragment like this is a national kind of act, even when it happens on a county road. It keeps a reference point — a way to answer the question of what the land actually looked like before people rebuilt it — and it recognizes that natural history and human history are the same story told from two sides.
If you visit
Come to Tridens Prairie the way you would come to an old cathedral: slowly, and ready to notice small things. There are no dramatic overlooks or monuments here. The spectacle is the grass itself — the way it moves in the wind, the astonishing variety packed into a single square yard, and the sheer fact that this is roughly what the horizon looked like when the Republic of Texas was new.
The prairie shows different faces through the year. In the warmer months, wildflowers thread through the grasses and the bunchgrasses stand tall; the palette shifts as the season turns. If you can, learn the name of one grass or flower before you go, then try to find it — the marker itself lists several, and spotting a long-spiked tridens turns an anonymous field into a place with characters.
Because this is a protected natural remnant under conservation management rather than a park built for crowds, treat access as something to confirm before you make the drive, and tread lightly if you do walk in. On a road trip through northeastern Texas, this is the stop that recalibrates your eye: pair it with the region's small-town history and you will see the farmland around you differently for the rest of the day, reading every plowed field as a place where a prairie used to be.

Smiley-Woodfin Native Prairie Grassland
Brookston, TX
At roughly 2,100 acres, the Smiley-Woodfin meadow is the largest surviving remnant of the vast native grassland that once rolled from Texas to Canada. A lack of fuel and surface water spared it the plow, and owner M. L. Smiley used it for grazing and hay while neighboring fields eroded under cultivation. After his death the land passed to the Woodfin brothers, and it remains the state's largest supplier of native hay.
Lamar County
Paris, TX
Carved from Red River County in 1840 and organized the following year, Lamar County honors Mirabeau B. Lamar, second president of the Republic of Texas and a champion of public education remembered as the 'Father of Texas education.' The county seat wandered in its early years — from Lafayette to Mount Vernon before settling at Paris, a town first known by the homely name Pinhook.
Campbell Cemetery
Paris, TX
Campbell Cemetery dates to 1843, when Texas was still an independent republic and Anglo settlement of the region was just taking hold. Though the marker records little beyond its founding and its Historic Texas Cemetery designation, the burial ground stands as one of the area's oldest, holding the earliest generations of local settlers.
Site of Lafayette
Paris, TX
In 1841, when Lamar County was newly organized in the young Republic of Texas, a plain clapboard courthouse rose on forty donated acres and became the county's first seat of government, a place called Lafayette. For two years justice was dispensed here under chief justice John A. Rutherford before the seat moved on and the town faded away. The State of Texas marked the spot in 1936 during its centennial, memorializing a vanished frontier community.
