The area now called Northridge was first inhabited about 2,000 years ago by the Native American Gabrielino (or Tongva) people. Totonga was their tribal village and where Northridge eventually became located. The Gabrielino-Tongva people, who lived in dome-shaped houses, are sometimes referred to as the “people of the earth.” They spoke a Takic Uto-Aztecan (Shoshonean) language.
It wasn’t until 1769 when the area known as Northridge was descriptively first reported by Father Juan Crespi, the prolific diarist who accompanied the exploration party of Spanish explorer Gaspar de Portolà on its arduous trek through California, including the Sepulveda Pass leading to the San Fernando Valley. Having traversed more than their share of dry and arid land, the discovery of water, wherever it was, merited rejoicing. And so it was with Zelzah, an unexpected oasis and one of the meeting places of the Gabrielino Indians, native to the area.[5] The explorers bathed and rested at the watering hole, fed by underground streams which still run deep beneath the intersection of Parthenia Street and Reseda Boulevard.
