For over seven thousand years, Native peoples have come to this exposed bedrock to fast, pray, seek visions, and carve their encounters with the spirit world. Dakota elders describe it as an encyclopedia of Native American history. The Thunderbird appears only three times. Turtles mark connections to the underworld.

Jeffers Petroglyphs has been used continuously for over seven thousand years, making it one of the oldest continuously used sacred sites in the world. The approximately five thousand carvings span from 5000 BCE to 1750 CE. The site is sacred to Dakota, Cheyenne, Arapaho, Ioway, and Ojibwe peoples, who help interpret it and continue to use it for ceremony.
Origin Story
The sacred character of this site predates human presence. The exposed quartzite of the Red Rock Ridge formed over a billion years ago, long before life existed on Earth. The red stone was here when the first humans arrived in this region after the last ice age. They recognized something in the stone worth reverence.
The earliest petroglyphs date to approximately 5000 BCE, carved by peoples whose names and languages have been lost. They came to this exposed bedrock, recognized it as sacred, and began the tradition of carving that would continue for seven millennia.
Who these earliest carvers were, what they believed, what specific meanings they attached to their images: these questions cannot be answered. The stone preserves their marks but not their words. What can be said is that they recognized this place as suitable for sacred communication, and their descendants agreed.

Spiritual Lineage
The Jeffers Petroglyphs participate in the broader tradition of rock art found across North America and worldwide. Indigenous peoples around the globe have used exposed rock surfaces for sacred marking, creating images that document their spiritual encounters. Within North America, the Jeffers site represents the largest collection of petroglyphs in the Midwestern United States. Similar sites exist across the continent, each with its own character and tradition, but Jeffers' combination of quantity, antiquity, and continuity is distinctive. The Dakota, Cheyenne, Arapaho, Ioway, and Ojibwe who maintain connection to this site are among the many Indigenous peoples who have used it over millennia. The specific chain of cultural transmission across seven thousand years is not fully documented, but the continuity is acknowledged. Contemporary Indigenous people recognize the ancient carvers as ancestors in spirit if not always in lineage.
