Community characteristics

Quartz Hill is located in the High Desert of California north of the Los Angeles area. As recently as the 1970s the town was largely agricultural, with cash crops of almonds, alfalfa and turkeys. The almond orchards being crippled by disease and the alfalfa growers having to contend with their water rights being diverted (to a growing Los Angeles) caused a significant shift in the local work force. The shift mainly was toward the nearby aerospace plants of Lockheed Martin and Rockwell International. Despite currently containing fewer orchards and farms than in its agricultural heyday, Quartz Hill still celebrates the Almond Blossom Festival every year.

Education

Quartz Hill schools include High Desert Bible College, Quartz Hill Elementary School, Sundown Elementary School, Joe Walker Middle School (students in parts of Quartz Hill go to Del Sur Elementary School in Antelope Acres), and Quartz Hill High School, which is part of the Antelope Valley Union High School District.
