California’s Blythe Intaglios: Massive Desert Figures Hidden in Plain Sight: What we know so far

Roughly 15 miles north of Blythe, California, six enormous shapes have been etched into the desert floor across two low mesas just off State Route 95 — and most people driving by have no idea they exist. From ground level, the markings appear to be nothing more than scattered rocks and compacted earth. Only from the air do the forms reveal themselves: human figures, four-legged animals, and a spiral, all arranged across the landscape in patterns that stretch dozens to hundreds of feet across. The largest human figure measures 171 feet from head to toe — more than half the length of a standard football field — while the other human forms each exceed 100 feet, and the animal figures span more than 50 feet wide.

No one has definitively established who created the Blythe Intaglios or precisely when. Scientists place their age somewhere between 450 and 2,000 years old, though that range itself remains contested. The construction method was straightforward: makers scraped away dark surface rocks by hand to expose lighter soil beneath, then arranged the displaced stones along the edges to define each shape. For centuries, only local Native peoples knew the figures were there. That changed in the early 1930s when a pilot flying over the area noticed shapes that seemed out of place on the terrain. His report prompted a formal survey, and a magazine feature in the 1950s eventually brought the intaglios to broader public attention. The Mohave and Quechan peoples, who have inhabited the Colorado River region across generations, connect the figures directly to their creation traditions — the human forms are said to represent Mastamho, creator of all life, while the animal figures depict Hatakulya, a mountain lion from their origin stories. Sacred ceremonies once took place near the site, and it continues to hold spiritual significance for tribal communities today.

Visitors are asked to show respect and leave no trace at the site, which still carries deep meaning for the Mohave and Quechan peoples whose traditions are reflected in the figures.

The Bureau of Land Management, which oversees the public land where the intaglios sit, erected fences around each figure group after vehicles and foot traffic caused damage to the fragile desert surface. Two of the three groupings are a short walk from a parking area reached by a dirt road off the highway, with marked trails and informational signs at each fenced location. A third group sits somewhat farther south. The site charges no entrance fee, keeps no posted hours, and requires no reservation — visitors can pull off the highway, walk to the edge of each fence, and view figures that have rested on this mesa for centuries. The Colorado River is visible to the east, and the Big Maria Mountains line the western horizon. Researchers continue to debate the figures’ precise age and origins, and no definitive answers have emerged. That unresolved history, set against an open and largely unchanged desert landscape, is what greets anyone who makes the short detour off Route 95 to see them.
