Las Moras Spring
Brackettville, Kinney County, Texas
Marker Inscription
As the ninth largest springs in Texas and the largest springs in Kinney County, Las Moras Spring is significant due to its location and invaluable natural resources. Moras, meaning “mulberries” in one Spanish translation, refer to the mulberry trees found along Las Moras bank. The spring discharges an average of 12-14 million gallons per day. Archeological objects such as flint points and burned-rock middens demonstrated that prehistoric people frequented Las Moras. In historic periods, the area was occupied by Coahuiltecan indians, hunter-gatherer tribes in the lower Pecos region, Apache, and Comanche. These groups stopped at Las Moras Spring while on trails into Mexico. The Annals of New Spain 1590-1771 record Europeans such as Gaspar Castaño de Sosa, Fernando del Bosque, General Alonzo de León and Field Marshal Señor Marqués de Rubí traveling to the spring. On October 13, 1840, Republic of Texas troops under Major John T. Howard attacked and destroyed a large Comanche village here at the spring. In 1848, Texas patriot Sam Maverick claimed the spring as part of his headright survey. By the next year, travelers on the New Military Road from San Antonio to El Paso were using the spring as a regular resting place for wagons bound for California. Fort Clark was established on June 20, 1852. The U.S. Army walled the spring pond in 1902 and created a swimming pool fed by the spring. The present pool was constructed for the army in 1939 through the Works Progress Administration (WPA) and is the largest ever built on any post. Las Moras Spring, supporting more than 11,000 years of human life, demonstrates the role of ecology in Texas’ development. (2013)

The Story
Las Moras Spring, the largest in Kinney County and ninth largest in Texas, has drawn people for more than 11,000 years, from flint-knapping prehistoric hunters to Coahuiltecan, Apache, and Comanche peoples following trails into Mexico. Spanish expeditions recorded stops here, and in 1840 Republic of Texas troops destroyed a Comanche village at the spring. Fort Clark rose beside it in 1852, and the Army later walled the pool and built a huge WPA swimming pool in 1939.
Why it matters
Reliable water shaped human movement across the Southwest for millennia, and this spring's long story shows how a single natural resource can anchor Indigenous, Spanish, and American history alike.
The story behind this marker
AI contextThe era
Long before there were forts or roads or borders here, there was water. In a dry corner of what is now Kinney County, Las Moras Spring rises with astonishing generosity — the ninth largest springs in Texas and the largest in the county, discharging, as the marker records, an average of twelve to fourteen million gallons a day. Its name traces to a Spanish word for mulberries, after the trees along its banks.
In arid country, a reliable spring is not a scenic amenity — it is the difference between passing through and staying alive. That single fact organized human movement across this region for thousands of years. Where the water was, the trails led; where the trails led, history followed.
The marker frames the spring as supporting more than eleven thousand years of human life, and that is the right scale to hold in mind. This is a place whose story is measured not in centuries but in millennia, with the same clear water at its center the whole way through.
People & events
The evidence of the earliest people here is written in stone and ash — flint points and burned-rock middens, the marker notes, left by prehistoric hunter-gatherers who returned to this water again and again. In historic times the area was frequented by Coahuiltecan peoples of the lower Pecos country, and later by Apache and Comanche, who stopped at the spring along trails that carried them into Mexico.
Then came the Europeans. The marker names a striking roster drawn from the Annals of New Spain — Gaspar Castaño de Sosa, Fernando del Bosque, General Alonzo de León, and the Marqués de Rubí among them — men whose expeditions across the northern frontier of New Spain brought them to this dependable water. In 1840, in the turbulent years of the Republic of Texas, troops under Major John T. Howard attacked and destroyed a large Comanche village at the spring, a violent episode in the long and painful contest over this land.
The American chapter followed quickly. In 1848 the Texas patriot Sam Maverick claimed the spring as part of his headright survey — the same Maverick whose name, through his own unbranded cattle, entered the American language. Within a year travelers on the New Military Road from San Antonio to El Paso were resting their California-bound wagons here, and in 1852 Fort Clark was established nearby.
Its place in the American story
The story of the American Southwest is, at bottom, a story about water. Empires, nations, and peoples did not move across this country at random; they followed the springs and rivers that made survival possible. Las Moras Spring is a compact, vivid illustration of that truth — a single source that drew Indigenous peoples, Spanish expeditions, and American soldiers and settlers alike.
What makes the site so telling is that all these histories layer onto the same spot. The same water that sustained prehistoric hunters later guided wagons toward California and anchored a frontier fort. Reading those layers in sequence is a way of watching the deeper forces of Southwestern history at work, stripped of the usual focus on any one people or era.
The marker's closing line captures it well: the spring demonstrates the role of ecology in Texas's development. It is a reminder that the human drama unfolding across the region was always shaped, first, by the map of where the water was.
If you visit
Come for the water, and let the sheer volume of it register. A spring pushing millions of gallons a day is a rare and vivid thing in dry country, and standing beside it you can immediately grasp why people have been drawn here for more than eleven thousand years. Look for the mulberry trees along the bank that gave the spring its name.
The site also carries a remarkable twentieth-century layer: the Army walled the spring pond in 1902 and created a swimming pool fed by its flow, and the pool you may see today was built for the Army in 1939 through the Works Progress Administration — the largest, the marker says, ever built on any post. It is a fascinating pivot, the ancient spring reshaped into a piece of Depression-era public works.
As you visit, try to hold the whole span at once: prehistoric knappers, Coahuiltecan, Apache, and Comanche travelers, Spanish expeditions, wagons bound for California, and soldiers cooling off in spring water on a hot afternoon. Access to sites like this can vary, so plan ahead — but however you come to it, this is a place best appreciated slowly, with the long view in mind.

Dolores Townsite
Brackettville, TX
In 1833 the English-born empresario John Charles Beales — holder of a staggering land grant across present-day Texas and New Mexico — led fifty-nine colonists to this spot to found a town named for his Mexican wife. Drought and Comanche raids battered the fragile settlement, and when the colonists fled south during the Texas Revolution in 1836, most of one party was killed on the road. The town never recovered.
Chalk Bluff Indian Massacre
Uvalde, TX
On May 29, 1861, two of southwest Texas's most noted frontiersmen were ambushed here by a band of some twenty Native warriors. Henry Robinson, a tall, red-bearded man so well known that his likeness had been painted on a rock near the Llano River, was traveling to Camp Wood with his companion Henry Adams when the attack came. Both men were killed and scalped, after which the raiders struck Robinson's home—only to be driven off by his family.
San Felipe Springs
Del Rio, TX
The seven San Felipe Springs have drawn travelers since at least 1542, and in 1675 Spanish priests named them for their king; in the 1700s Comanches camped here along a war trail into Mexico, and a mission rose downstream in 1808. By the 1850s the springs lay on the vast San Antonio–to–San Diego mail route and the Chihuahua Road, where wagons hauled Mexican silver and gold toward the Gulf port of Indianola. After settlers arrived in 1864 and dug the 'Mother Ditch' for irrigation, the town of Del Rio soon took root.
Site of Camp Del Rio
Del Rio, TX
Established as Camp San Felipe in 1876 as an outpost of Fort Clark, this U.S. Army post was one of a chain of forts defending the isolated settlements of the Southwest Texas frontier. General E. O. C. Ord created it to guard against raiding parties crossing the Pecos and Devil's Rivers. After the town of Del Rio grew up around it, the camp took the town's name; with the end of Indian raids by 1890, troops moved on and the post was abandoned in 1891.
