Bering Strait, 21,000 years ago to present. Ocean waters were about 400 feet lower than they are today at the time of human migration across the Bering Land Bridge.

Early man migrated across the so-called Bering Land Bridge from Siberia, traveled down the west
coast of North America and fanned out across the current United States and into Mexico approximately
13,000 years ago. The identity of the earliest humans in the Santa Clarita Valley — and what
language they spoke — is unknown. They predated the Tataviam, who spoke
a Uto-Aztecan language, by about 11,000 years.
