Native American History

Weatherford, TX

Created in 1855 on land once granted to Stephen F. Austin and S.M. Williams, Parker County had barely settled before the Civil War split it, voting 535 to 61 for secession in 1861. Its men supplied Confederate beef, rode against frequent Comanche and Kiowa raids, and sent nine companies to the war, while local rancher John R. Baylor even became Confederate governor of Arizona.

Perry Township, PA

For countless generations, Native people came to the rocks along the Allegheny River near here to carve images of humans, animals, mythical beings, and abstract shapes. The number and variety of these petroglyphs, set against an undeveloped landscape, make the site remarkable. Now submerged for most of the year, the carvings preserve the legends and beliefs of people who lived and traveled through Pennsylvania thousands of years ago.

Parsippany-Troy Hills, NJ

Long before New Jersey had roads or towns, Indigenous people sheltered beneath this rock outcrop and pecked carvings into its stone, leaving behind some of the only known petroglyphs in the state. Archaeologists trace the rockshelter back roughly three thousand years, to Woodland-era peoples who used such overhangs as seasonal camps. The markings are a rare surviving record of a culture that inscribed meaning directly onto the landscape.

Menard, TX

In 1753 Spanish explorer Juan Galvan raised a great cross at this river ford to mark his chosen site for Mission San Saba. Indigenous people gathered at the cross and took part in what is remembered as the first Christian worship service in the area. Both the mission, two miles east, and the ford took their names from the Holy Cross.

Enochs, TX

From the 1840s through the 1890s, Hispanic sheepherders from New Mexico known as pastores drove great flocks into the grasslands of the Llano Estacado and Bailey County, following La Vista de Vida Agua—the Trail of Living Water—from spring to spring. They borrowed routes first blazed by ciboleros (bison hunters) and Comancheros (traders) who had long done business with the Native peoples of the plains. Their stone corrals, boxed-in springs, and rock shelters still dot the land where the sheep industry endured into the 1930s.

Walker Township, PA · est. 1947

In the mid-1750s the Juniata Valley was a raw and dangerous edge of Pennsylvania's frontier, where scattered settler families lived within reach of raiding parties as the French and Indian War set the backcountry aflame. Around 1755 Captain James Patterson threw up a timber stockade on high ground above the Juniata River, serving as both its builder and commandant—one link in a chain of private and provincial forts that gave neighbors a place to shelter when alarms swept through. Such refuges were rough affairs of sharpened logs and blockhouses, but for a farm family with minutes to flee, they meant the difference between survival and disaster.

Lower Paxton Township, PA · est. 1947

Somewhere near this spot stood Patton's Fort, a base for the Paxton Rangers who patrolled the gaps of the Blue Mountains during the French and Indian War. From the Susquehanna River to Swatara Creek, these frontier militiamen guarded farmsteads and mountain passes against raids between 1756 and 1763. Theirs was a grinding, dangerous vigil along an unsettled border.

Margaret, TX

On this ground in December 1860, Texas Rangers under Captain L. S. Ross overtook a Comanche encampment and recaptured Cynthia Ann Parker, who had been taken as a child during a raid in 1836 and raised among the Comanche for twenty-four years. Torn from the family she had made—including her son, the future chief Quanah Parker—her recapture became one of the most famous and tragic episodes of the Texas frontier. The state marked the battlefield in 1936.

Crowell, TX

At the Battle of Pease River in 1860, Texas Rangers under Captain L. S. Ross attacked a Comanche encampment and took a woman they recognized as Cynthia Ann Parker, seized as a nine-year-old in the 1836 raid on Fort Parker. By then she had lived a quarter-century among the Comanche as Naduah, wife of Chief Peta Nocona and mother of the future leader Quanah Parker. Returned to her Anglo relatives with her infant daughter, she never adjusted, tried repeatedly to escape, and died in 1864.

Menard, TX

This hourglass-shaped pass where McDougal Creek meets the San Saba River was a favored Native American campground long before it entered written history in 1732 as the site of a Spanish-Apache battle. Over the following generations it saw mustang hunters, Indian fighters, German settlers, and gold-seekers pass through, and it became a stagecoach station named—so the story goes—for a one-legged land commissioner. Its nearby 'Robbers' Roost' gained notoriety for hold-ups, and the crossing later served the Great Western Cattle Trail.

Center Point, TX

The Penateka, or "honey eaters," were the southernmost band of the Comanche, ranging across the Edwards Plateau and following the buffalo on which they depended for food, clothing, and shelter. Renowned horsemen, they made settlement west of this area perilous for decades. Pressure from Texas Rangers and the U.S. Army's Second Cavalry, reservation removals, and the Red River War of 1874–75 forced the Comanche onto reservation lands, where the breakup of holdings in 1901 scattered the people — who have since worked to rebuild their shared culture.

Penitas, TX

Peñitas—"Little Pebbles," named for local gravel—grew from the mid-18th-century colonization of José de Escandón, who in 1749 settled families on the Reynosa land grant along the Rio Grande. On the common lands north of the river, ranching communities took root, protected by the small mission of San Joaquín del Monte that ministered to Indigenous people and settlers alike. A prosperous salt trade, Spanish porciones granted in the 1760s, and later a steamboat landing and railroad stop carried the community into the modern era.

Mission vicinity, TX

By local tradition, Penitas was founded in the mid-1520s by Father Zamora and five Spaniards who broke away from the ill-fated Pánfilo de Narváez expedition, making it, some claim, among the oldest towns in the United States. The refugees are said to have built whitewashed stone houses and been befriended by Native people, exchanging the Catholic faith, weaving, and farming methods for lessons in local cookery. Whether legend or fact, the story links this Rio Grande settlement to the earliest chapters of Spanish contact in the New World.

Duncanville, TX

Two springs feeding a natural pool made this a vital watering place, first for Native peoples and later for the wagon trains and cattle drives moving along the Shawnee Trail. Major John Penn of Illinois settled his family here in the 1850s after first visiting in 1848, and on July 4, 1882, the springs hosted a Confederate reunion of Parson's Texas Cavalry. The Penns held the land until 1895 as Duncanville grew around it.

Philadelphia, PA · est. 1976

This riverside Philadelphia park marks the traditional site where William Penn is said to have met with the Lenape and other Native peoples to affirm peaceful relations. No signed document survives, but the memory of Penn's dealings became a founding legend of Pennsylvania's Quaker experiment. The city has kept the ground as a green space honoring that story.

Monroe Township, PA · est. 1947

On October 16, 1755, a war party struck the scattered settlers along Penns Creek, killing, wounding, or carrying off some two dozen people. Coming just weeks after General Braddock's catastrophic defeat near Fort Duquesne, it was the first such attack to fall on the Pennsylvania frontier as the French and Indian War spilled eastward. The raid shattered the colony's fragile peace and sent shockwaves through the backcountry.

Monroe Township, PA · est. 1919

In October 1755, along the banks of Penn's Creek, frontier families were attacked and roughly two dozen settlers were killed, wounded, or carried off into captivity. The raid came just months after General Edward Braddock's disastrous defeat near the Monongahela, which shattered British prestige and emboldened France's Native allies. It is remembered as the first such outbreak of frontier violence within Pennsylvania during the French and Indian War.

Philadelphia, PA · est. 2012

Built about 1697 where a Lenape trail forded Pennypack Creek, this modest triple-arched stone span is reckoned the oldest roadway bridge in continuous use in the United States. It carried the King's Highway, one of colonial America's great overland routes, and in 1781 bore the tramp of American and French troops marching south with Rochambeau toward the decisive siege of Yorktown. Widened only once, in 1893, its upstream face looks much as it did when William Penn's colony was young.

Churchill County, NV

This broad valley sits in the Great Basin, where rivers vanish into terminal sinks rather than reaching the sea, and where the vast Ice Age Lake Lahontan once spread its waters. For some 12,000 years Native peoples lived here, thriving when wetlands filled the basins; from wave-cut caves like Leonard Rock Shelter and Lovelock Cave, archaeologists have recovered nets, fishhooks, duck decoys, and basketry. By the time American explorers arrived in the 1830s, the wetlands still sustained villages of the Numa, the Northern Paiute.

Redmond, WA

A planted willow marks Perrigo Springs, a natural water source that quenched the thirst of Native people long before it served the early settlers of Redmond, Washington. Placed by the Daughters of the American Colonists in 2004, the marker points to a spot where the region's history flowed—literally—through a shared spring. In the days before wells and pipes, such springs decided where trails ran and where towns took root.

Forestburg, TX

The oldest marked grave in this Montague County burial ground belongs to an infant who died in 1862, and its early plots read like a chronicle of frontier hardship: a well-digger killed in an 1863 Indian raid, and two former Confederate soldiers who had been captured at Lookout Mountain. In 1883 Levi Perryman — himself a Confederate veteran, Indian fighter, and sheriff — bought the site and deeded it to the county. Still in use, the cemetery keeps the memory of the district's pioneers.

Coatesville, PA · est. 1954

Peter Bezellon was a noted Indian trader and interpreter in colonial Pennsylvania who bought a 500-acre tract in this area in 1736, part of which includes this site. Traders like Bezellon lived at the meeting point of two worlds, moving goods and words between colonial settlers and Native nations in the decades of early contact along the frontier. He died in 1742 and lies buried with his wife, Martha, in St. John's churchyard at Compass.

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.

Philipsburg, PA

In 1797, the year the young United States was still finding its footing, twelve families pushed into the dense central Pennsylvania forest at the invitation of Henry Philips, who offered them free land. They settled along the Moshannon Creek among towering old-growth timber, carving out a foothold in country still shared with the Seneca followers of the Iroquois leader Cornplanter. The little settlement they raised, first called Moshannon Town, grew into the borough of Philipsburg.

Liberty Township, PA · est. 1966

In July 1780, as the Revolution's violence spilled across the Pennsylvania frontier, Captain William Phillips and eleven men of his militia company were captured near this spot by a Native war party. Ten were killed and later buried by a search party, while Phillips and his son Elijah were taken prisoner and not freed until the British released them at war's end.

Marietta, OH

This stone marks the southern corner of the palisaded, or "picketed," defensive point where Marietta's early settlers sheltered during the Indian War of 1791–1795 — the frontier fighting that followed the founding of Ohio's first permanent American settlement. Behind such stockades families lived under threat during years of conflict between the new settlers and the Native nations of the Ohio country. The Woman's Centennial Association placed the marker in 1903, and its reverse recalls the Marquis de Lafayette's landing at Marietta.

Breckenridge, TX

One of Stephens County's first Anglo settlements, Picketville rose on Gunsolus Creek just before the Civil War, its name likely drawn from the picket-style cabins of upright, mud-chinked timbers. Left without military protection during the war, families "forted up" here for safety against Indian raids. It served as county seat until Breckenridge was founded in 1876, after which it faded away, leaving only a cemetery that Boy Scouts later restored and fenced.

Maple Grove, MN

Pierre Bottineau (1817–1895) was a Métis fur trader, guide, and townsite promoter whose knowledge of the northern plains made him one of frontier Minnesota's most sought-after pathfinders. Fluent in numerous languages, he helped guide expeditions and lay out settlements as the region shifted from fur-trade country to farms and towns. His preserved house recalls the mixed Native and European world that shaped Minnesota's founding generation.

Bethel Township, PA · est. 1950

In 1742, Count Nicholas von Zinzendorf, the Moravian leader traveling among the Native peoples of Pennsylvania, paused at this spring along the Tulpehocken Path and named it "Pilgrim's Rest." The path was an ancient Indian route linking European settlements to the Native towns of Shamokin and Wyoming, and Zinzendorf's journey was part of the Moravians' extensive missionary work among the region's Indigenous nations.

Shippen Township, PA · est. 1951

Long before roads crossed these ridges, the Seneca and other Iroquois peoples moved along well-worn footpaths linking the Genesee country of New York to the Susquehanna. One such trail reached south toward Jersey Shore before splitting near here—one branch threading the dramatic gorge of Pine Creek, the other climbing over the hills by way of Darling Run and Babb Creek. These routes carried trade, diplomacy, and daily life through the northern Pennsylvania wilds.

Sayre, PA · est. 1947

Pioneers called this stretch of open pineland the 'Pine Plains,' and in 1790 it witnessed a moment of early American diplomacy: Timothy Pickering, on behalf of the new federal government, met the Seneca leader Red Jacket and his people here as they traveled to a peace council at Tioga Point. Such councils were the young republic's effort to secure its northern frontier through negotiation rather than open war with the Iroquois nations.

Weches, TX

Long before Europeans arrived, the Tejas Indians favored this spring-fed grove for its game and fresh water, and the site kept drawing travelers for centuries afterward. Sitting beside El Camino Real — the King's Highway that linked Spanish missions and presidios across the province — it hosted explorers, missionaries, traders, and later the wagon trains of 19th-century pioneers who circled up in the trees to rest. Hunting parties would camp here for weeks at a stretch well into the settlement era.

Navajo County, AZ

This site marks an early trading post at Piñon, on the Navajo Nation in northeastern Arizona, established as the community first took shape before it was formally organized. Trading posts were the commercial and social hubs of the reservation, places where Navajo weavers, silversmiths, and herders exchanged goods with traders and the wider market economy reached remote high desert country.

Sisterdale, TX

Where the old Pinta Trail forded the Guadalupe River, the Hill Country frontier found one of its key landmarks. In October 1839 a Republic of Texas expedition of surveyors, Texas Rangers, and volunteers gathered near here, stacked a pile of rocks on the north bank to mark their starting point, and ran a fifty-mile survey line northeast through the wilderness. The ranger and surveyor Jack Hays returned to plot land grants around the crossing, a nearby creek took the name of a man killed on the expedition — giving Sisterdale its namesake — and by 1847 German immigrants bound for Fredericksburg were using the same ford, with Nicolaus Zink settling as the area's first resident.

Boerne, TX

The Pinta Trail was a natural Hill Country pathway used first by Native Americans and later by the Spanish, running some 180 miles from San Antonio to the 1750s presidio at Menard. In the 1780s pathfinder José Mares folded it into a shorter Santa Fe–San Antonio route, and in 1839 Jack Hays surveyed its Guadalupe River crossing as the "Paint Road." German Adelsverein colonists used the trail in the 1840s to reach their new Hill Country settlements, and it appears in the era's maps, surveys, and even landscape paintings.

Fort Davis, TX

Used from the 1870s until 1914, this Fort Davis graveyard holds the memory of the frontier: the Belgian-and-Spanish Dutchover family, whose coined surname still endures among their descendants; a bride named Dolores, said to have burned mountain signal fires for a lost love for thirty years; and two Frier brothers shot as horse thieves. It reads as a roll call of the hazards and legends of far West Texas settlement.

Cross Plains, TX

The Pioneer community took shape in the 1880s, though the earliest burial here—Mrs. S.A. Briggs in 1879—predates it, and the landowners formally deeded the ground in 1906. An oil boom in the 1920s swelled the population by thousands before production waned and the railroad and most settlers moved on. Among those resting here is Catherine Martin O'Neal Lovett, a Cherokee survivor of the 1838 Trail of Tears, alongside a war memorial the local quilting club raised in 1948 for soldiers lost in the World Wars.

Winnemucca, NV

This corner of the pioneer cemetery holds the founders of Winnemucca, a Humboldt River town first known as French Ford. Frank Baud, who arrived in 1863, helped name the settlement after the noted Northern Paiute chief Winnemucca. Baud came to work on Dr. Gintz's ambitious but never-finished 90-mile Humboldt canal, then became a merchant, the town's first postmaster, and the donor of its schoolhouse before his death in 1868.

El Paso, TX

Pioneer Plaza was the beating heart of early El Paso, a shaded, tree-lined square where military bands played and a U.S. Army guard stood watch in the late 1870s against Apache raids. Great overland arteries met here — El Paso Street running south to Mexico, San Francisco Street west toward California, and the Butterfield stage line clipping its corner — making it a true crossroads of the Southwest. In 1909 Presidents Taft and Díaz swept through the plaza en route to their historic border summit before the little square was eclipsed by larger San Jacinto Plaza.

Richland, TX

Pisgah Ridge, a limestone outcropping named for the biblical Mount Pisgah, long drew people to its caves, creeks, and game. In 1830 Cherokees reportedly burned a village here that had been shared by Tonkawa and Tawakoni people, and within a few years settlers of European descent arrived, building a stagecoach inn and small communities along the Springfield Road. The area gained a rough reputation from a family feud and its links to outlaw John Wesley Hardin before the railroad bypassed it in the 1870s and drew residents away.

Lower Southampton Township, PA · est. 1925

In the earliest years of Penn's colony, an Unami Lenape community known as Playwicky stood in the vale by the run and springs south of here. Their leader was Tammany, a chief of the Turtle clan who became famous for his dealings with William Penn and, later, as a folk symbol of American liberty. In 1683 he and his people sold Penn the land between the Neshaminy and Pennypack Creeks.

Princeton, TX

Pleasant Grove Cemetery took its first burial in 1891 with Malissa Sides, believed to be half Native American and a survivor, with her Cherokee half-sister, of the U.S. government's removal of the tribe. The pair came to Collin County from Indian Territory, and later that year a Methodist family donated the land — including Mrs. Sides' grave — as a public burial ground. Among its thousand-plus graves lie 141 infants, testament to harsh pioneer life, alongside Confederate and other war veterans.

Groesbeck, TX

L. T. M. Plummer and his wife Rachel, born a Parker, reached this part of Limestone County in 1834 and received a Mexican land grant of over 3,000 acres. In the 1836 raid on Fort Parker, Rachel, her son James, and her cousin Cynthia Ann Parker were taken captive by Comanches; Rachel was ransomed in 1838 but died within a year, as did her infant son Wilson. Grieving, L. T. M. set aside an acre as a family burial ground, where more than a hundred Plummer descendants now rest.

Livingston, TX

Polk County was carved from Liberty County and organized in July 1846, with Livingston as its seat, in the first months after Texas joined the Union. It was named for President James K. Polk, whose administration championed the annexation of Texas. Early settlements clustered at river landings like Drew's Landing and Swartout, and on land granted by the state in 1854 the descendants of the Alabama Indians still make their home.

Livingston, TX

During the Civil War, Polk County was a stretch of piney woods, farms, and thickets that included an Alabama-Coushatta reservation. Though it counted only 600 voters in 1860, it sent some 900 soldiers into the Confederate Army, furnishing four companies to Hood's famed Texas Brigade and organizing several other infantry units; twenty-one Alabama-Coushattas enlisted in an Indian cavalry company. On the home front, old men, women, children, and enslaved people raised food and cotton, while the county's ferries and river landings moved troops and supplies until Livingston became headquarters for the federal Army of Occupation in 1867-68.

Edgar County, IL

This marker commemorates the July 18, 1765 peace council between the Ottawa chief Pontiac and British agent George Croghan, which helped bring an end to the sweeping Native uprising against British rule that followed the French and Indian War. Pontiac's War had erupted as Indigenous nations resisted harsh British policies and encroachment after France's defeat, and Croghan's negotiations were pivotal in restoring an uneasy peace.

Shiner, TX

Virginians William and Isabella Ponton came to Texas in 1829 and received land in DeWitt's Colony, where William became the first recorded settler killed by Comanche in what became Lavaca County; his son Joel later survived an attack with two arrows in his back. The family stood with their neighbors at the Battle of Gonzales, fled in the Runaway Scrape after the Alamo fell, and returned to rebuild after San Jacinto. Across the eras of the Republic, statehood, and the Civil War, the Pontons served as alcaldes, judges, doctors, preachers, and peacemakers.

Stephenville, TX

Pioneers began building homes in the Pony Creek Community around 1845, though frontier conditions — including raids by Native war parties — kept life precarious until after the Civil War. The cemetery's oldest marked grave belongs to J.T. Roberson (d. 1875), and another early stone remembers Martha Walker Bills, born in 1799. John and Mary Britton formally deeded the land in 1907, and the burial ground, long tied to the Pony Creek Baptist Church founded in 1865, still preserves the names of the agricultural families who worked this land.

Weatherford, TX

Robert Scott Porter, the first judge of Parker County, set aside this ground near his cabin as a family cemetery in 1867 after the death of his three-year-old granddaughter. Frontier violence marks the plot: the judge's grandson, and his daughter Mary with her husband and child, were killed by Indians and buried here. Of perhaps fifty burials only twenty-eight are identified, among them the judge and his wife Nancy Ann, whose descendants restored the cemetery in 1976.

Pacifica, CA

On November 4, 1769, a Spanish overland expedition led by Gaspar de Portolá, searching for Monterey Bay, instead climbed these coastal hills and became the first Europeans to sight the vast San Francisco Bay. The 'discovery' of one of the world's great natural harbors — long known to the Ohlone people who lived along its shores — reshaped Spain's plans for Alta California and led within a few years to the founding of the San Francisco presidio and mission.

Florence, AZ

Charles Debrille Poston (1825-1902), often called the 'Father of Arizona,' lobbied during Lincoln's administration for the federal legislation that created the Arizona Territory in 1863, driven in part by his silver-mining interests. Over his career he served as Superintendent of Indian Affairs, U.S. Land Register at Florence, consul at Nogales, and Arizona's first congressional delegate. He dreamed of a temple to the sun on a nearby hill and was buried atop this butte, which now bears his name.

Sangamon County, IL

Between September and November of 1838, more than 800 Potawatomi people were forced at gunpoint from their Indiana homelands and marched hundreds of miles west to Kansas, a journey remembered as the Trail of Death. This marker stands at the Island Grove encampment, one of the overnight stops where the exhausted column paused as illness and grief took their toll. It is one of many placed along the route to keep the removal from being forgotten.

Sangamon County, IL

During the 1838 Potawatomi Trail of Death, the forced removal column that carried more than 800 people from Indiana toward Kansas halted at a series of encampments, including this one at McCoys Mill. Marched under armed guard through the late-summer heat and autumn cold, the Potawatomi endured sickness and death along the way. This marker commemorates one of those grim overnight stops.

Amarillo, TX

The land that became Potter County lay in country ranged by Apache, Arapaho, Cheyenne, Comanche, and Kiowa peoples and crossed by old Spanish and trail routes, including the Great Spanish Road of 1786 and the Fort Smith–Santa Fe Trail followed by 1849 gold seekers. Created by the legislature in 1876 while still empty, it saw Indigenous peoples forced out and buffalo replaced by longhorns, the great LX and barbed-wire Frying Pan ranches established, and finally organized by cowboy voters in 1887. Named for Republic of Texas official Robert Potter, it later gave up the vast Panhandle-Hugoton gas field and holds the Alibates flint quarries worked by prehistoric peoples as early as 10,000 B.C.

Mandeville, LA

Pottery Hill, shaded by the ancient Castain Oak, holds layered evidence of human life reaching back to the late Tchefuncte era around 800 BC and the early Marksville period of the first centuries AD. Pottery shards, bone, and shell deposits show that Native peoples — including the Acolapissa and later the Choctaw — used this ground continuously into the 20th century. Colonial settlers later prized its fine clay, running commercial potteries here until the 1940s.

Pottsboro, TX

Before Anglo settlers arrived, the Caddo and Wichita peoples occupied this stretch of North Texas. The town took shape when Confederate veteran and land developer James A. Potts, who had come to Grayson County in 1868, deeded a railroad right-of-way to a Missouri-Kansas-Texas subsidiary in 1878 and platted the townsite that bears his name. Incorporated in 1885, Pottsboro survived repeated fires and later drew new life from the 1940s construction of Perrin Army Air Field and Lake Texoma.

Gladstone, OR

The old Pow-Wow Tree marks a gathering place used for Indian councils and, in 1861, the site of the first Oregon State Fair. In the years just after Oregon's 1859 statehood, such shade trees often served as natural meeting halls where Native peoples and settlers alike assembled for talk, trade, and celebration. The spot layers Indigenous council traditions with the earliest civic pageantry of the young state.

Clark County, NV

On August 30, 1869, Major John Wesley Powell and his weary crew reached the mouth of the Virgin River, completing the first expedition through the Grand Canyon of the Colorado. They had launched from Green River City, Wyoming Territory, three months earlier, enduring rapids, hunger, and the unknown to survey and study the great river canyons. Near starvation at journey's end, the party was fed by Mormon farmers at nearby St. Thomas. The original settlement and river junction now lie beneath Lake Mead.

Imperial County, CA

Erected by the Imperial Valley Pioneer Association in 1955, this marker traces a footpath used long before European arrival, running from the Colorado River across the desert to what was once Lake Cahuilla—the huge freshwater lake that periodically filled the Salton basin. For countless generations, Indigenous peoples of the lower Colorado followed such routes between water, trade, and seasonal camps across one of North America's harshest landscapes.

Seabrook, TX

For centuries, Native peoples harvested rangia clams from Galveston Bay and discarded the shells here, building up a "shell midden" that eventually grew large enough to serve as the foundation for a substantial campsite. Stone tools and pottery found in the mound reveal later occupation, and while the earliest inhabitants can't be named, both the Orcoquisac and Karankawa are known to have lived in the area in historic times. Storms, erosion, and shell mining have destroyed most such sites, making this one of Harris County's best surviving examples.
