About 15 miles north of Blythe, just west of U.S. Highway 95 near the Colorado River, the Blythe Intaglios (or Blythe Geoglyphs) decorate the desert floor. These six enormous ground designs, in three locations, remain one of the enduring historic mysteries of the United States. They represent a human figure at each location and animal figures depicting serpents and quadrupeds at the other two sites. No one knows precisely who created them or when.
