Hemet Maze Stone, Ancient petroglyph site near Hemet, California, United States

Hemet Maze Stone is a protected area in California containing an ancient rock carving with an intricate maze pattern. The pattern consists of two concentric rectangular boxes centered within the rock surface.

The Hemet Maze Stone is a prehistoric petroglyph in Reinhardt Canyon, in the Lakeview Mountains of Riverside County. On April 16, 1956, Mr. and Mrs. Rodger E. Miller donated the stone and 5.75 acres of surrounding land to Riverside County, and it became California Historical Landmark No. 557. At some later point a vandal added a counter-clockwise swastika to one corner of the carving.

The carving is classified as California Engraved, within the California Tradition of rock art. A vandal later added a counter-clockwise swastika to one corner; the clockwise version was the one adopted in Germany, while swastikas appear in Oriental and Native American art long before that. Look for the plaque reading "MAZE STONE" on the boulder's lower left.

The stone sits at the end of California Avenue, north of Highway 74 and several miles east of Interstate 215 in Reinhardt Canyon. The access road has been blocked off so vehicles cannot drive up to the boulder; visitors continue on foot. Two chain-link fences enclose the petroglyph, and the surrounding land is set aside for native plants and animals, with a posted warning that natural features may be hazardous.

A counter-clockwise swastika was carved into one corner of the petroglyph by a vandal sometime after 1956. It is not part of the original work; the Nazi version used after World War I runs clockwise, while swastika motifs appear in Asian and Native American art long before that.
