Great Salt Lake
Raymondville, Willacy County, Texas
Marker Inscription
Here has existed since the first Spanish chronicler traversed the region, A great salt lake which supplied all northern Mexico with salt. (1936)
Erected by Texas Historical Commission
The Story
Since the days of the first Spanish chroniclers passing through the region, a great salt lake here yielded salt that supplied much of northern Mexico. In an age before refrigeration, salt was essential for preserving meat and hides, making such natural deposits a prized resource. The lake tied this corner of South Texas into trade networks reaching deep across the border.
Why it matters
Natural salt sources were strategic economic assets from the Spanish colonial era onward, and this lake shows how geography shaped commerce along the Texas–Mexico frontier for centuries.
The story behind this marker
AI contextThe era
Long before there was a Texas or a United States, the brushlands of what is now far South Texas were part of the northern frontier of New Spain. Spanish explorers, missionaries and chroniclers crossed the region in the colonial era and recorded what they found, including valuable natural resources.
One of those resources was salt. According to the marker, a great salt lake existed here from the time of the first Spanish chronicler's journey, and it supplied salt to all of northern Mexico. In a world without refrigeration, salt was essential. It preserved meat, cured hides, seasoned food, and was used in mining and other industries.
That made a natural salt deposit a strategic economic resource. Control of salt and access to it mattered to colonial officials, ranchers and traders across the region, and the trade tied this part of South Texas to communities far to the south.
People & events
The marker doesn't name individual people, but it describes a long parade of them. First came the Spanish chroniclers who noted the lake on their travels. Then, for generations, came the people who harvested the salt and carried it south to supply towns, ranches and households across northern Mexico.
Harvesting salt from a natural lake was hard, practical work. Salt left behind by evaporation could be gathered and loaded for transport, and the trade routes that carried it helped bind the borderlands together economically long before a modern international border divided them.
The marker itself has a history. It dates from 1936, the year Texas celebrated the centennial of its independence with a statewide program of historical markers and monuments. Its authors chose to honor a natural resource rather than a battle or a famous person, a sign of how much the salt lake had meant to the region over the centuries.
Its place in the American story
The salt lake is a reminder that American history in the Southwest started with Spanish colonial history. Long before Anglo-American settlers arrived, the region was part of a Spanish world with its own roads, trade and economic ties reaching deep into Mexico.
Salt has shaped history around the world, and North America is no exception. Natural salt sources drew people, created trade routes and became valuable prizes. This lake shows how geography could shape commerce across a whole region for centuries.
It also shows how interconnected the Texas–Mexico borderlands have always been. The salt that went from here to northern Mexico traveled through a region with shared culture and commerce. The international border came later, and the connections it crosses are much older.
If you visit
Stop here to think about deep time. The marker points back past Texas statehood and past Mexican independence, to Spanish travelers crossing this flat brush country and taking note of a lake that gave salt.
The landscape around Raymondville is low, open and dry-edged, the kind of country where a natural salt deposit would stand out and be worth remembering. Notice how flat it is and imagine carts loaded with salt starting the long trip south.
This marker fits well on a Rio Grande Valley road trip that explores the region's Spanish and Mexican heritage. Pair it with missions, ranch sites and border towns to see how the borderlands developed over centuries, and remember that ordinary things like salt were once treasures worth crossing a continent for.

Hilltop Gardens
Monte Alto, TX
Founded in 1939 by Lee and Sherman Ewald on a hilltop north of La Villa, Hilltop Gardens became one of the first commercial aloe vera farms in the United States, pioneering the crop's cultivation in the Rio Grande Valley. Lee Ewald developed aloe-gel cosmetics with her daughters, marketing them through a company incorporated in 1962 in what is believed to be a first use of aloe gel as a cosmetic ingredient. Under later owners the farm grew to hundreds of thousands of plants and became part of a major aloe-producing corporation, opening to the public in 2012 with the largest U.S. collection of aloe species.
El Sal del Rey
Linn, TX
On the South Texas plains northeast of Linn lies a natural salt lake the Spanish claimed for the crown upon its discovery in 1746, invoking the old principle that salt itself was a form of money. For generations people across a wide region hauled away salt from its shores, and during 1863–64 its works helped supply Confederate Texas. Later legal battles over who owned the lake helped shape the state's foundational laws on private mineral ownership.
Laguna Seca Ranch
Linn, TX
Macedonio Vela settled this stretch of brush country in 1867 and turned more than 4,000 acres into the flourishing Laguna Seca ("Dry Lake") Ranch, which eventually swelled to 80,000 acres. In 1871 his daughter Carlota planted the first orange trees in Hidalgo County from seeds a traveling priest had given her—an early spark for what became a major citrus region. A school, post office, and Catholic church soon followed, and the ranch remains in Vela hands generations later.
San Perlita "Pearl of the Valley"
San Perlita, TX
Once part of the Spanish-era Carricitos land grant, San Perlita blossomed as a farming community after the Missouri Pacific Railroad reached the area in 1926. The San Perlita Development Company cleared more than twenty thousand acres for cotton, vegetables, and citrus and laid out the townsite. The "Pearl of the Valley" has contributed to Rio Grande Valley agriculture ever since.
