Timeline of the Portolá expedition
This timeline of the Portolá expedition tracks the progress during 1769 and 1770 of the first European exploration-by-land of north-western coastal areas in what became Las Californias, a province of Spanish colonial New Spain. Later, the region was administratively-split into Baja (lower, see Baja California peninsula) and Alta (upper, see Alta California).
