Geological Riches of Moore County
Dumas, Moore County, Texas
Marker Inscription
Have proved beneficial from earliest times when prehistoric man developed first industry in Texas by mining flint deposits along the Canadian River. Items made from these quarries have been found over a large portion of the western United States. Slabs of dolomite from area were used to build sturdy, warm homes; interiors were coated with mixture of sand, clay and caliche -- an advance uncommon in prehistoric North America. Modern man has established 31 industries based on oil and gas, to take advantage of geological riches untapped by ancient man. (1970)

The Story
The land around Dumas has been prized for its geology far longer than any oil derrick suggests. Prehistoric peoples mined flint from quarries along the Canadian River — an early Texas "industry" whose tools turn up across the western United States — and built sturdy, insulated homes from local dolomite slabs, an unusually advanced technique for the era. Centuries later, modern Moore County tapped a different underground treasure, oil and gas, to support dozens of industries.
Why it matters
It links the oldest human industry on the Southern Plains to the modern energy economy, showing how the same ground rewarded very different peoples across thousands of years.
The story behind this marker
AI contextThe era
The land around Dumas sits in the Texas Panhandle, near the Canadian River, where the ground itself has shaped human life for a very long time. Long before oil derricks or county lines, the river valley offered something precious: high-quality stone.
According to the marker, prehistoric peoples worked flint deposits along the Canadian River — an activity the marker frames as an early Texas "industry." The Canadian River country is well known for its ancient flint quarries, and the durable, colorful stone drawn from them was valued far and wide for making tools and weapons.
Much later, the same region entered a very different era. The marker, erected in 1970, describes a modern Moore County built on oil and gas — a Panhandle transformed by the twentieth-century energy economy. Two ages of resource-hungry people, drawn to the very same patch of earth for very different reasons.
People & events
The marker's story has no single hero; its subject is the ground and the generations who read its value. First come the prehistoric quarry workers, chipping stone from the riverside deposits. The marker notes that items made from these quarries have turned up across a large part of the western United States — a striking sign of how far the stone, or the people who carried it, once traveled.
The marker also credits these early inhabitants with a clever kind of home-building: slabs of local dolomite used to raise sturdy, warm houses, their interiors coated with a mixture of sand, clay, and caliche. The marker calls this an advance uncommon in prehistoric North America — a 1970 assessment worth reading as the marker's own framing rather than a settled verdict, but a genuine tribute to the ingenuity it honors.
Then the story leaps across the centuries to "modern man," who by 1970 had established dozens of industries built on oil and gas — the marker counts 31 — to reach the geological riches that ancient people never touched. That number is a snapshot of the county at the time the marker was placed, not a running tally.
Its place in the American story
This little marker quietly makes a big point: America's story on this land did not begin with settlers or drilling rigs. It began thousands of years earlier, with people who understood the value of what lay beneath their feet and turned it into tools that spread across the West.
The famous flint of the Canadian River is part of a much larger truth about the continent — that early peoples ran sophisticated networks of quarrying, crafting, and long-distance exchange. Stone from a single stretch of river could end up hundreds of miles away, evidence of connections that reached far beyond any one community.
By pairing that ancient stonework with the modern oil-and-gas economy, the marker frames the Panhandle as a place defined across all its eras by what the earth provides. It's a distinctly American arc: the same ground rewarding utterly different peoples, each drawing wealth from the layers below.
If you visit
You're in the wide, open country of the Texas Panhandle here, where big skies and long horizons dominate and the modern economy runs on oil and gas. Let the marker reset your sense of time: the landscape you're looking at was an industrial resource for people thousands of years ago.
As you read, hold the two ages side by side — the ancient quarries and dolomite homes on one hand, the derricks and pipelines of the modern county on the other. The marker's real gift is that double vision, the reminder that "industry" here is far older than any machine.
If you're driving the Panhandle, let this stop change how you see the land between towns. Those flat miles are not empty; they are layered with deep human history and deep geological wealth. Keep an eye on the country near the Canadian River, and remember that the stone underfoot once traveled farther than most people ever did.

Site of Historic Drift Fence
Dumas, TX
Before the mid-1880s the Texas Panhandle had no range fences, so winter blizzards drove cattle south from Oklahoma, Colorado, and Kansas onto Texas ranges, mixing the herds and overgrazing the Canadian River breaks. To stop the costly spring separations, ranches like the Turkey Track, LX, and LIT joined to build a 200-mile, four-strand barbed-wire drift fence — until an 1889 state law against fencing public land forced most of it down by 1890.
City of Dumas
Dumas, TX
In 1891 Louis Dumas and J.R. Wheat organized a townsite company on the high, dry plains of the Texas Panhandle and named the new community for Dumas himself. A post office arrived that year, county-seat status the next, and a bank by 1908—yet the arid land drew few settlers and the town stayed small. Everything changed when oil was discovered in 1927, transforming Dumas's fortunes almost overnight.
Moore County
Dumas, TX
Carved from the Bexar Land District in 1876 and formally organized in 1892, Moore County took its name from Edwin W. Moore, commodore of the Republic of Texas navy. In its early days stagecoaches and freight wagons crossed a thinly settled Panhandle where ranching was nearly the only livelihood. That changed sharply after oil and gas were struck in 1926, and the county's economy grew into petrochemicals, helium, cattle feeding, and grain.
Masterson
Masterson, TX
In 1927 three companies joined forces to build a natural gas plant and pipeline carrying fuel all the way to Denver, and a small company town of workers' cottages, a hotel, and a one-room school grew up around it, first called Bivins. World War II brought a second boom: a federal Bureau of Mines helium plant opened nearby in 1943, ringed by seventy-five new homes and a recreation hall for the Exell workers. Renamed Masterson after the post office rejected "Bivins," the community thrived until the 1960s, when residents were told to move on and the twin camps emptied by 1970.
