Miami Mammoth Kill Site
Miami, Roberts County, Texas
Marker Inscription
In 1933, a local farmer plowing a wheat field began uncovering large, chalky bones. Knowing them to be too large to be cow or buffalo bones, several area residents, including county judge and amateur archeologist J.A. Mead, investigated the site and made a significant discovery; a man-made stone artifact was found alongside the bones of what were mammoth elephants. The investigators identified the artifact as a Clovis fluted spear point, similar to items discovered in 1932 at the Blackwater draw site near Clovis, New Mexico. In 1934, Dr. E. H. Sellards of the University of Texas became involved. Securing funding through the Works Progress Administration, he led an extended excavation of the Miami site beginning in 1937. Landowner C.R. Cowan asked only that the site be refilled following the dig. Known initially as the C.R. Cowan site, the Miami site was found to be a playa lake filled with blue clay up to about two feet below ground level. The clay had formed from vegetation that once the pond. The remains of three to five adult mammoths, as well as the bones of at least one baby mammoth, were found at this site. Among the bones were man-made hunting tools, such as a spear point found less three inches from a mammoth’s atlas vertebra. Archeologists found two other spear points and hide scraping tool. The artifacts alongside the bones indicate that the animals were killed at a watering hole. The evidence is significant, showing the contemporary existence of man and mammoth in North America. It also demonstrates that early man was an efficient, experienced hunter, information that has been used in the debate over the causes of extinction of late Pleistocene era animals approximately 12,000 years ago. The site remains one of the most significant early man sites in North America. (2003)

The Story
In 1933 a Panhandle farmer plowing wheat turned up chalky bones far too big for any cow or buffalo. Local investigators, and later University of Texas scientist Dr. E.H. Sellards with WPA funding, uncovered the remains of several mammoths lying beside Clovis fluted spear points — one resting just inches from a mammoth's vertebra. The find placed human hunters and mammoths together at an Ice Age watering hole roughly 12,000 years ago.
Why it matters
The Miami site is one of North America's most important early-human discoveries, offering rare hard evidence of Paleo-Indian hunters and fueling the enduring debate over what drove the great Ice Age animals to extinction.
The story behind this marker
AI contextThe era
The story of the Miami site runs on two clocks. The deep one goes back to the end of the last Ice Age, when the High Plains were cooler and wetter. Mammoths, ancient bison and other huge animals moved across grasslands dotted with shallow lakes and watering holes. People were there too, the early hunters archaeologists call Paleo-Indians.
The second clock is the 1930s. The Texas Panhandle was wheat country, and it was also the heart of the Dust Bowl and the Great Depression. That hard era explains part of how the site was excavated. The Works Progress Administration, a New Deal program built to put unemployed Americans to work, funded many archaeological digs across the country, and this was one of them.
The timing mattered for science as well. For decades many experts had doubted that people had lived in North America during the Ice Age at all. In 1927, spear points found with extinct bison near Folsom, New Mexico, began to change their minds. The Clovis discoveries at Blackwater Draw in the early 1930s pushed the evidence further back. Miami arrived just as the question was opening up.
People & events
It began with a plow. In 1933 a farmer working a wheat field turned up large, chalky bones, much too big for a cow or a buffalo. Curious neighbors came to look. Among them was J.A. Mead, a county judge who was also an amateur archaeologist, and they found something that turned a curiosity into a discovery: a stone spear point lying with what proved to be mammoth bones.
The investigators recognized it as a Clovis fluted point, like the ones found the year before near Clovis, New Mexico. In 1934, Dr. E.H. Sellards of the University of Texas took an interest. He secured WPA funding and led a longer excavation beginning in 1937. The landowner, C.R. Cowan, made one simple request, that the site be filled back in afterward, and for a while the place carried his name.
The diggers found an ancient playa lake filled with blue clay. In it lay the remains of three to five adult mammoths and at least one baby. With the bones were hunting tools, including a spear point less than three inches from a mammoth's atlas vertebra, the bone at the top of the neck. Two more spear points and a hide-scraping tool completed the picture: people had brought these animals down at a watering hole.
Its place in the American story
Miami is one of the places that settled a basic question in American history, whether humans and mammoths lived on this continent at the same time. Here the answer is written in stone and bone, and it is yes. The site helped confirm that people were living and hunting across North America near the end of the Ice Age.
It also shows what those people were like. These were not desperate scavengers. They were skilled, organized hunters with carefully made weapons who could take down animals many times their size. That picture changes the long story of human life in the Americas.
The site also feeds one of the great open questions in natural history: why mammoths and many other large Ice Age animals disappeared around 12,000 years ago. Some scientists stress climate change, others stress human hunting, and many think both played a part. The debate is not settled, and evidence from places like Miami is still part of it.
If you visit
Set your expectations honestly. There is no dig to see and no bones in the ground on display. At the landowner's request the site was filled back in after the excavation, so the marker is how you pay your respects here. Do not go looking for the old dig on private land.
The marker still rewards the stop. Stand in the quiet Panhandle landscape and picture it as it was, with a shallow pond, grass around the shore, and a small band of hunters closing in on a mammoth at the water's edge. The spot's modesty is part of its power, because this ordinary-looking farmland once held evidence that changed the history of a continent.
Miami is a tiny town in wide-open country. Combine the stop with a drive through the Canadian River breaks, and if the Ice Age has caught you, add Blackwater Draw near Clovis, New Mexico, to a longer High Plains trip.

Gen. Nelson Miles Expedition (Headquarters Dugout)
Canadian, TX
In the winter of 1874–75, the U.S. Army swept the Texas Panhandle in the campaign now known as the Red River War, and General Nelson Miles ran part of it from a dugout post near here. His columns fought eight engagements that season and, in November 1874, recovered two of the captive German sisters, Addie and Julia, with their older sisters freed the following February. From this rough headquarters Miles nominated soldiers for the Medal of Honor, among them the celebrated scout Billy Dixon, before Fort Elliott rose in 1875 to carry on the work.
Peter W. Gray
Pampa, TX
Virginia-born Peter W. Gray came to Texas in 1838 and became a leading figure of the Republic and state, serving as district attorney, judge, Texas Supreme Court justice, and legislator. A delegate to the Secession Convention, he later served the Confederacy, and in 1864 became Treasury Agent for the Trans-Mississippi region, in effect running Confederate finances for a war-torn territory dependent on smuggled currency, blockade-runners, and couriers. Gray County was named in his honor, and the state erected this memorial to him in 1963.
Rescue of Two White Girls by Lt. Frank Baldwin
Pampa, TX
On November 8, 1874, during the Red River War against the Southern Plains tribes, Lieutenant Frank D. Baldwin led two companies of U.S. troops in an attack on a large Cheyenne band about ten miles southwest of here, freeing two young girls held captive. The clash came amid the army's final campaign to force the Cheyenne, Comanche, and Kiowa onto reservations and open the Texas Panhandle to settlement.
Site of Fort Elliott
Mobeetie, TX
Established in June 1875, Fort Elliott was among the last military posts built in Texas as the U.S. Army sought to force Indigenous peoples off the Panhandle plains. Around its walls sprang up Mobeetie, a rough rendezvous for buffalo hunters and traders, until the fort was abandoned in 1889 and the frontier era it enforced drew to a close.
