Around 500 B.C., a band of Shoshonean-speaking Indians established settlements in what is now the San Gabriel Valley. These Native Americans were dubbed the Gabrieliño Indians (after San Gabriel, the local mission) by early Spanish colonial explorers, but now generally prefer to be called the Tongva. Since the San Gabriel Valley area was home to large numbers of oak trees such as coast live oak and interior live oak, a staple of the Tongva diet was an acorn meal made by boiling acorn flour.
