Sebastián Vizcaíno
In 1542, Juan Rodríguez Cabrillo traversed the coast of California and named many of its features. In 1601, Sebastián Vizcaíno mapped the coastline in detail and gave new names to many features. Martín de Aguilar, lost from the expedition led by Sebastián Vizcaíno, explored the Pacific coast as far north as Coos Bay in present-day Oregon.
