Blythe Intaglios

The Blythe Intaglios or Blythe Geoglyphs are a group of gigantic figures incised on the ground near Blythe, California, in the Colorado Desert. The ground drawings or geoglyphs were created by humans for an, as yet, unknown reason.

The intaglios are located east of the Big Maria Mountains, about 15 miles north of downtown Blythe, just west of U.S. Highway 95 near the Colorado River. The Blythe Intaglios are the most well-known of the over 200 intaglios in the Colorado Desert. The Colorado Desert contains the only known desert intaglios in North America. These intaglios are mostly located along the Colorado River.
