Estimates for the position of sea level during the Holocene vary significantly.

Santarosae Island was a single Pleistocene-to-early-Holocene island formed by San Miguel, Santa Rosa, Santa Cruz, and Anacapa islands in the Santa Barbara Channel. Anacapa was isolated first (ca. 9000 B.C.), followed by Santa Cruz (ca. 7800 B.P.) and the separation of Santa Rosa and San Miguel (ca. 7600 B.C.).
