Twin Chimneys
Post, Garza County, Texas
Marker Inscription
(100 Yards North) Used as a landmark in the 19th century by surveyors sighting from Duffy's Peak, located ten miles northeast. Jasper Hays, earliest recorded surveyor of this area, used the peaks during 1877-78 for charting the Llano Ranch, later bought by C. W. Post, the cereal king. Hays established, in addition, lines from which section surveys were made. Civil engineer A. L. Marhoff, using the original field notes and book of Hays, surveyed the land bought by Post, 1906. This included the section on which the town of Post was founded, 1907, as well as other property. 1970

The Story
These twin peaks served as a surveyor's landmark in the nineteenth century, sighted from Duffy's Peak ten miles northeast. Jasper Hays, the earliest recorded surveyor here, used them in 1877–78 to chart the Llano Ranch — land later bought by cereal king C. W. Post — and to establish the base lines for section surveys. Using Hays's original field notes, engineer A. L. Marhoff resurveyed Post's purchase in 1906, including the section where the town of Post was founded in 1907.
Why it matters
Survey landmarks like Twin Chimneys made the orderly division and settlement of the West possible, turning open range into mapped, saleable land.
The story behind this marker
AI contextThe era
In the late 1870s the country around present-day Post, Texas, was still open range at the edge of the Llano Estacado, the vast high plain of West Texas. The Red River War of 1874–75 had ended Comanche and Kiowa control of the southern plains. Ranchers, surveyors and land companies moved quickly into country that had barely appeared on Anglo-American maps.
Texas had a special relationship with its land. When it joined the Union it kept its public lands, and the state used them to pay for railroads, schools and other public projects. To grant or sell that land, someone first had to measure it. Surveyors went out into empty country and turned it into numbered sections and blocks that could be recorded, bought and sold.
On a treeless plain, surveyors depended on landmarks: hills, buttes and peaks visible from miles away. Twin Chimneys was one of them, and so was Duffy's Peak about ten miles to the northeast. Distinctive points like these anchored the lines that divided a whole region.
People & events
The first figure in this story is Jasper Hays, the earliest recorded surveyor of the area. In 1877 and 1878 he used these peaks as sighting points while charting the Llano Ranch. Working with instruments, chains and careful notes, he sighted from high ground and laid out lines across country with few other fixed features. He also set the base lines from which later section surveys were run. That foundational work quietly shaped every land title that followed.
Decades later the land changed hands in a way nobody on the survey crews could have predicted. C. W. Post, the Michigan businessman who made a fortune in breakfast foods and coffee substitutes and became known as "the cereal king," bought the Llano Ranch property. He had big ideas for West Texas. He wanted a planned town and farms for settlers on land he controlled.
To carry out those plans, Post needed accurate boundaries. In 1906 civil engineer A. L. Marhoff surveyed the land Post had bought, working from Hays's original field notes and book. Nearly thirty years after the first survey, Hays's notes were still the authority that tied the new survey to the old one.
Marhoff's survey covered the section where the town of Post was founded in 1907, along with other property. A town that still carries Post's name began on lines first sighted from these twin peaks.
Its place in the American story
Twin Chimneys shows one of the least glamorous but most important parts of westward expansion: the survey. Before farms, fences, railroads or towns, land had to be measured and recorded. The surveyor's chain and field book did as much to settle the West as the plow and the railroad. They turned open range into property that could be owned, taxed, mortgaged and sold.
The story also shows how Eastern industrial wealth reached into the West around 1900. C. W. Post made his money selling packaged breakfast foods to a national market, then spent some of it building a planned community on the Texas plains. Across the West, business fortunes bought land and remade it, often in visionary and experimental ways.
Finally, the chain from Hays to Marhoff shows how much depends on good records. A surveyor's notebook from the 1870s was still the legal foundation for a town founded in 1907. Much of the American map rests on the same kind of patient, careful paperwork.
If you visit
The marker notes that the landmark itself stands about 100 yards to the north. Look in that direction and picture yourself as a surveyor on an open plain, hunting for any fixed point to sight on. Then try to imagine Duffy's Peak ten miles off, and a line running between the two across country that had no roads or fences yet.
This is big-sky country at the edge of the Caprock, where the high plains break down toward rougher land. It rewards anyone who likes wide views and changing light, especially early or late in the day. Keep to public areas and respect private ranchland.
The town of Post is the natural next stop. It's a place whose very existence traces back to the surveys remembered here, and its founder's name is still on the map. Twin Chimneys makes a thoughtful short stop on a West Texas drive, especially if you're traveling between the Rolling Plains and the Llano Estacado.

J. M. Boren Home
Post, TX
Built in 1908 from lumber hauled 75 miles across the open plains, this home belonged to J. M. Boren — Garza County's first county judge, as well as a rancher, bank director, and civic leader. Its hospitality was well known to the pioneers and cowboys who passed through the young town of Post. The house reflects the determination it took to build a settled community on the West Texas frontier.
C. W. Post Home
Post, TX
Cereal-foods millionaire C. W. Post built this home in 1912 in the very town he founded, planting a colony on the West Texas plains that he stocked with settlers by selling land on generous terms and seeding new industries. True to his slogan "I Want Quality," he fitted the house with solid oak doors, redwood floors, and leather wallpaper. Post was as much a town-builder as a breakfast magnate, promoting agriculture and settlement across the region.
Verbena Community Church
Post, TX
Built in 1904, the Verbena Community Church replaced a simple brush arbor that had sheltered summertime services for settlers of every denomination. On the wind-scoured plains it doubled as a refuge during blizzards, with one rule for those who took shelter: chop enough wood to warm the next stranded traveler who might come after. It was recorded as a Texas Historic Landmark in 1964.
Mason Memorial Building
Post, TX
Dedicated to Garza County pioneers Marshall and Gladys Mason, this building was donated by their children for use as a community museum and recognized as a Recorded Texas Historic Landmark in 1967. It honors the settler families who helped establish this corner of the West Texas plains in the early 20th century. The gift turned a family memorial into a public keeper of local history.
