Travel 230 miles north of Los Angeles to Owens Valley at the foot of the Sierra Nevada Mountain range and you will find a white concrete obelisk with black Japanese writing rising out of the desert. Only a few simple gravestones stand in the background a few feet away. Today, the obelisk is one of the few remaining structures from the Manzanar War Relocation Center—an American concentration camp where Japanese Americans were held during World War II.
