El Encino del Poso (The Oak in the Hole)
Encino, Brooks County, Texas
Marker Inscription
In this vicinity once stood a magnificent live oak tree that was an early landmark on the South Texas Plains for many years. Noted for its size and its wide canopy, it was located in a large hollow created by livestock that gathered beneath its branches and by winds that eroded the exposed soil. El Encino del Poso was a landmark for early trails and land grants. It also served as the location of a stagecoach station and as the basis for naming Encino (1 mi. N). The tree died in the 1890s, before the formation of Brooks County, the victim of an extended drought. Texas Sesquicentennial 1836-1986

The Story
A magnificent live oak once spread its canopy over this stretch of the South Texas plains, growing in a hollow scooped out by sheltering livestock and eroding winds. "The Oak in the Hole" guided early trails and land grants, sheltered a stagecoach station, and gave the nearby town of Encino its name. An extended drought killed the great tree in the 1890s.
Why it matters
Natural landmarks like this oak served as the road signs of the frontier, orienting travelers and settlers long before fences and highways divided the land.
The story behind this marker
AI contextThe era
The South Texas Plains are big, open country: brush, grassland, and sky stretching toward the Rio Grande. For much of the nineteenth century this was ranching land, organized around large Spanish and Mexican land grants long before Anglo-American settlers arrived in large numbers. Water was precious, distances were long, and there were few landmarks for a traveler to steer by.
In that setting, a single great tree could matter enormously. Before fences, surveyed roads, and highway signs, people found their way by natural features: a creek crossing, a hill, a grove, or one unmistakable oak. Land grant boundaries were often described by landmarks like these, and trails bent toward them because everyone knew where they were.
As the century went on, stagecoach lines carried mail and passengers across the region, and settlement slowly grew. The area around the oak was still part of a larger county then. Brooks County would not be created until after the tree was gone.
People & events
The central character of this story isn't a person. It is a tree. El Encino del Poso, "the oak in the hole," was a magnificent live oak famous for its size and its wide, sheltering canopy. Its odd name came from where it grew: in a large hollow. Cattle and other livestock crowded into its shade for generations, trampling and loosening the ground, and the wind carried away the exposed soil until the great tree stood in a bowl of its own making.
People gathered here too. Travelers used the oak to find their way along early trails, and it served as a reference point for land grants. Eventually a stagecoach station stood at the site. You can imagine drivers pulling in beneath its branches to change horses, passengers stretching their legs in the rare shade, and news passing between strangers. The oak lent its name to the community of Encino, about a mile north.
Then, in the 1890s, an extended drought struck the region, and the ancient tree died. It was a hard reminder that even the grandest landmark on these plains depended on rain. The tree was gone before Brooks County was formed, but its name survived in the town it helped create.
Its place in the American story
El Encino del Poso is a local example of something that happened all across the American frontier: natural landmarks served as the first road signs. From lone trees on the plains to famous rock formations along the western trails, travelers, surveyors, and settlers relied on distinctive natural features to navigate and to divide the land.
The story also points to South Texas's layered history. Its land grants and its Spanish place name, Encino meaning oak, reflect the Spanish and Mexican foundations beneath later American settlement. Understanding this region means understanding those deep Hispanic roots, which are central to the history of the American Southwest.
Finally, the oak's death in a drought fits into a larger story about the land itself. Drought shaped ranching, settlement, and survival across the Great Plains and the Southwest, and a changing landscape could erase even a famous landmark within a single generation.
If you visit
The tree itself is long gone, so come with your imagination ready. Stand near the marker and look out across the flat, brushy plains. Picture a huge live oak rising out of a hollow, its limbs spreading wide, with cattle bunched in its shade and a stagecoach rolling in along the trail.
Notice how scarce big trees are on this landscape. That is the best way to understand why one great oak could guide travelers for miles, and why a whole town took its name.
Encino sits on a main north–south route through deep South Texas, so this is an easy stop on a drive toward the Rio Grande Valley. Bring water and sun protection, since the plains can be hot and exposed. Take a quiet moment here, a place where the landmark disappeared but the name endures.

Falfurrias
Falfurrias, TX
Falfurrias was founded in 1904 as a cattle-shipping point by rancher Edward C. Lasater, who took the name from a village on land he had bought in 1893. When the San Antonio & Aransas Pass Railroad reached the area, Lasater platted the townsite and built its hotel, store, water and power plants, and cotton gin, then opened the region to truck farming, citrus, and dairying — founding South Texas' first creamery. Later oil and gas discoveries added yet another chapter to the boomtown's growth.
The Armstrong Ranch
Sarita, TX
This land, part of the Spanish "La Barreta" grant, was purchased in 1852 and became home to famed Texas Ranger John Barkley Armstrong after his 1878 marriage to Mollie Durst. Armstrong had ridden with Captain McNelly to bring order to South Texas and won national fame for capturing the outlaw John Wesley Hardin. On this ground—once a camp for Zachary Taylor's army and a stage stop between Corpus Christi and Brownsville—he built one of the legendary cattle ranches of Texas, still run by his descendants.
Kenedy County
Sarita, TX
Kenedy County was carved from Cameron, Willacy, and Hidalgo counties in 1921 and named for Mifflin Kenedy, who came to Texas in 1846 aboard U.S. Army supply boats and went on to become a leading commercial navigator of the Rio Grande. Kenedy built a steamboat and ranching empire along the lower river before his death in 1895, and the tiny town of Sarita serves as the seat of the sparsely peopled county that bears his name. The county's late creation reflects the slow settlement of the vast South Texas ranchlands.
Edward Burleson Raymond
Raymondville, TX
Born in an Austin log house to a Republic of Texas newspaperman, E. B. Raymond rode into South Texas in 1870 and spent decades managing the sprawling King-Kenedy ranching empire. Building his own ranch and civic career, he helped bring the railroad through by deeding right-of-way and donating a station site, which the railway named in his honor. He then founded a town company, bank, telephone exchange, and cotton gin, and Raymondville later became the seat of Willacy County.
