Old rock courthouse still stands in present Frio Town. The county has had four courthouses: two frame ones, one of rock, and one of brick. In 1876 a Texas Ranger camp, under the noted Major John B. Jones, was set up on Elm Creek to protect settlers from Indian attacks. The legendary frontiersman W.A.A. "Big Foot" Wallace (1817-1899) spend his last years in Frio County. (1968)

The Story
Though Spanish explorers passed through this brushy South Texas country as early as 1690, Frio County was not organized until after the Civil War. The county seat shifted from Frio City to Pearsall when the International & Great Northern Railroad arrived in 1883, and in 1876 a Texas Ranger camp under Major John B. Jones guarded settlers against raids. The legendary frontiersman "Big Foot" Wallace spent his last years here.
Why it matters
Frio County's story captures the frontier phase of Texas settlement—rail lines, Ranger patrols, and colorful frontiersmen shaping a raw borderland into organized counties.
The story behind this marker
AI contextThe era
The brushy, sun-baked country of South Texas has a longer recorded history than most travelers expect. Spanish explorers passed through this region as early as 1690, making it one of the first parts of Texas to be seen by European eyes. Yet exploration is not settlement, and for well over a century this remained frontier land—open, contested, and sparsely peopled.
Frio County itself was created in 1858, on the eve of the Civil War, but it was not formally organized until 1871, in the years after the war. That timing tells the story of the whole region: the real business of building counties, towns, and courthouses in this part of Texas belonged to the Reconstruction and Gilded Age decades, when settlers pushed into country that was still genuinely wild.
This was borderland in every sense—far from the settled east, exposed to raids, and only slowly knitted into the fabric of an organized state. It was a place where the frontier was not a memory but a daily reality.
People & events
The county's early decades read like a frontier chronicle. Frio City, laid out in 1871, was the first county seat—but its reign was brief. When the International & Great Northern Railroad arrived, the town of Pearsall rose along the tracks, and in 1883 it took the county seat away. It is a classic Texas tale: the railroad, not the older settlement, decided where power and prosperity would settle. The old rock courthouse still stands in present-day Frio Town, and over the years the county has raised four courthouses in all—two of frame, one of rock, and one of brick.
Protection was a constant concern. In 1876 a Texas Ranger camp was established on Elm Creek under the noted Major John B. Jones, tasked with guarding settlers against Indian raids. Jones was a significant figure in the Ranger service of that era, and the presence of such a camp underscores how unsettled this frontier still was in the 1870s.
And then there is the legend. The frontiersman W.A.A. "Big Foot" Wallace, who lived from 1817 to 1899, spent his last years in Frio County. Wallace was one of the great characters of early Texas, and his choice to end his days in this rugged country gives the place a colorful, almost storybook connection to the vanishing frontier.
Its place in the American story
Frio County's story is a compact version of a much larger American drama: the transformation of raw borderland into organized, settled country. The elements are all here—the railroad that reshaped the map, the mounted lawmen who patrolled a dangerous frontier, and the larger-than-life frontiersman living out his final years.
The arrival of the International & Great Northern Railroad and the subsequent rise of Pearsall mirror what happened across the West, where rail lines determined which towns thrived and which faded. A county seat could shift overnight because a railroad chose one route over another. That was the engine of settlement, and Frio County lived it directly.
The Ranger camp on Elm Creek connects this quiet county to the broader, and often difficult, history of westward expansion—the long, contested process by which settlers, Native peoples, and government forces met on the frontier. It is a story of both nation-building and displacement, and markers like this one preserve the local texture of an era that shaped the whole country.
If you visit
Begin, if you can, with the old rock courthouse still standing in Frio Town—a tangible survivor of the county's first decades and a reminder that Pearsall was not always the center of things. From there, the county opens up as a landscape of frontier history: the brushy country the Spanish first crossed in 1690, the creeks where Rangers once camped, and the railroad town that reshaped it all.
As you travel, keep in mind the four courthouses—frame, rock, and brick—that mark the county's growth from raw settlement to established community. Each was a statement of permanence in a place that had known very little of it.
This is a rewarding stop for anyone drawn to the frontier chapter of Texas history, where the past isn't behind glass but written into small towns, old buildings, and the wide South Texas horizon. Read the marker, then look around: the country itself still carries the feel of the borderland it once was.

Frio County
Pearsall, TX
Long home to the Pachal Indians, this South Texas country was first crossed by Spanish explorer Alonso de León in 1690 as he searched for La Salle's ill-fated Fort St. Louis. By 1720 the route through the region had become part of a King's Highway linking Saltillo to East Texas—the same road along which Santa Anna marched toward the Alamo in 1836. Frio County, named for its "cold" river, was created in 1858 and organized in 1871, its seat later moving to Pearsall in 1883.
Devine Evergreen Cemetery
Devine, TX
The earliest graves in this Medina County cemetery belong to settlers killed by Native American raiders in the early 1870s, including seventeen-year-old Isaac Galbreath, whose father — a Texas Ranger and Mexican War veteran — also rests here. The town of Devine grew up in 1881 when the International and Great Northern Railroad reached the area, and landowner P.C. Hattox deeded the original acreage for the cemetery in 1891. A cemetery association has cared for the grounds ever since.
Chihuahua Trail
San Antonio, TX
Long before wagons, this corridor was an Indigenous road threading from the San Antonio country west toward the Pecos and south through Presidio into northern Mexico. Water was scarce enough that travelers reportedly chewed leather to fight thirst while oxen bolted at the first scent of a spring. From 1835 onward, Texans turned the route into a commercial artery, and during the Civil War it carried scarce goods like rope, shoes, and salt past the Union blockade.
Site of Fort Inge
Uvalde, TX
Fort Inge was established in 1849 by Captain Sidney Burbank and named for Lieutenant Zebulon M. P. Inge, killed at Resaca de la Palma in 1846. Set on the Texas frontier near Uvalde, it guarded the southern Overland Mail route against raids and sheltered travelers and troops through the mid-nineteenth century. Abandoned during the Civil War, it was reoccupied by federal troops from 1866 to 1869 and later served as a Texas Ranger camp.
