Early Explorers in Llano County
Llano, Llano County, Texas
Marker Inscription
By commission of the Governor of Spanish Texas, Bernardo de Miranda in 1756 examined Cerro del Almagre, a red ochre hill supposedly rich in silver. His party of 23 from San Antonio struck Honey Creek near here, then went to the junction of the Llano and Colorado rivers. Three pounds of ore from Cerro del Almagre assayed only ten ounces of silver to 100 pounds of ore. Plans for further explorations were therefore abandoned as such low yield; coupled with transport problems and Indian threats, made mining seem unattractive.

The Story
In 1756, under commission from the governor of Spanish Texas, Bernardo de Miranda led a party of 23 from San Antonio to examine Cerro del Almagre, a red-ochre hill rumored to be rich in silver. Reaching Honey Creek and the junction of the Llano and Colorado rivers, Miranda gathered ore that assayed at only ten ounces of silver per hundred pounds. That meager yield, combined with transport difficulties and the threat of Native raids, led Spain to abandon plans for further mining.
Why it matters
Miranda's expedition marks Spain's early, ultimately fruitless reach into the Texas Hill Country in search of mineral wealth — a reminder of how imperial dreams shaped, and often bypassed, the frontier.
The story behind this marker
AI contextThe era
Long before Texas was American — before it was even independent or Mexican — it was a far northern frontier of the Spanish empire. In the mid-1700s, Spanish Texas was governed from San Antonio, and the Crown's officials kept a keen interest in any rumor of mineral wealth that might justify pushing settlement and control deeper into the interior.
The Hill Country around the Llano and Colorado rivers lay at the edge of that reach. It was rugged, distant, and dangerous, held by Native peoples and only lightly touched by Spanish authority. A hill of red ochre in this country had gathered a reputation for hidden silver — exactly the kind of prospect that could set an expedition in motion.
In 1756, under commission from the governor of Spanish Texas, that prospect drew an official party north to see whether the legend held any truth.
People & events
The expedition was led by Bernardo de Miranda, who set out from San Antonio with a party of 23 to examine Cerro del Almagre — the red-ochre hill said to be rich in silver. The group struck Honey Creek and then made for the junction of the Llano and Colorado rivers, moving through country that was both promising and perilous.
Miranda gathered ore to be tested, and the assay told a disappointing story: three pounds of ore from the hill yielded only about ten ounces of silver per hundred pounds — far too little to justify the enormous cost and risk of mining there.
That single result effectively ended the venture. The meager yield, combined with the difficulty of transporting anything across such distance and the threat of Native resistance, made further mining look unattractive. The dream of silver in the Llano hills quietly collapsed under the weight of its own arithmetic.
Its place in the American story
Miranda's 1756 expedition is a small, telling chapter in the vast story of European empires searching North America for precious metals. From the earliest Spanish entradas onward, rumors of gold and silver drove exploration far beyond the reach of settlement — and far more often than not, those rumors proved hollow.
The episode also marks how early the recorded history of central Texas reaches back. Decades before the American Revolution, Spanish officials were already probing these hills, leaving a documentary trail that predates the Anglo-American story of Texas by generations.
And it is a case study in why frontiers stayed frontiers. Distance, transport, danger, and thin returns repeatedly defeated imperial ambitions in the interior. The land that looked like opportunity on a governor's map turned out, again and again, to resist the empires that reached for it — a pattern that shaped where colonization took hold and where it did not.
If you visit
This marker sits in Llano County, in the heart of the Texas Hill Country, where the granite-and-ochre landscape still hints at the mineral hopes that once drew explorers here. The country around the Llano and Colorado rivers is beautiful and rugged — a fine place to imagine a small Spanish party picking its way north in 1756.
As you take in the terrain, think about the enormous gap between rumor and reality that this story turns on. The same distances and rough ground that make the region so scenic today are precisely what defeated the dream of silver mining more than two and a half centuries ago.
The marker rewards a traveler curious about the deep, Spanish-colonial roots of Texas history — a layer older than most visitors expect. Pair it with a broader Hill Country drive around Llano, and let it reframe the landscape as a place that empires reached for, tested, and ultimately let be.

Llano City Cemetery
Llano, TX
Founded in 1856 as the seat of new Llano County, the town soon needed a burial ground, and by 1862 it held its first graves — a one-year-old child and a seventeen-year-old girl whose stones still stand. Trustees formalized the cemetery in the 1880s before deeding it to the city in 1907. Among those resting here is Frank Teich, the stonecutter remembered as the father of Texas's granite industry.
Bluffton Cemetery
Llano, TX
When the damming of the Colorado River created Lake Buchanan in the 1930s, entire cemeteries in the flood's path had to move. This site, donated in 1930, received relocated graves from the Old Bluffton Cemetery and several others, their reburials carried out in stages from 1931 to 1937. Among the first new interments was Ike Maxwell, who had named the Bluffton community in 1854 and, as a legislator, helped choose native granite for the state capitol.
Christian-Matern House
Marble Falls, TX
When Marble Falls was founded in the 1880s, Juliet Johnson — daughter of the town's founder — married George Christian, one of the ten men whose Texas Mining & Improvement Company platted and promoted the new town. This fine Queen Anne house was built for the couple in 1892, all decorative woodwork and protruding bay windows. In 1908 it passed to merchant and rancher Ivo Matern, later mayor of Marble Falls, whose family kept it for fifty-one years.
Site of Mormon Settlement
Marble Falls, TX
In 1851 some twenty Mormon families led by Lyman Wight settled here on the Texas frontier, building homes, lumber mills, and furniture shops. Wight, a former lieutenant of Joseph Smith who broke with Brigham Young's church, led his followers through a series of short-lived Texas colonies, and this one lasted only until 1853. The state marked the vanished settlement in 1936.
