Spanish explorer Gabriel Moraga entered the region in 1808, naming the valley "Sacramento Valley" in honor of Sacramento, the Holy Sacrament in Spanish, giving the northerly city of Sacramento its name. A writer on Moraga's expedition wrote of the region: "Canopies of oaks and cottonwoods, many festooned with grapevines, overhung both sides of the blue current. Birds chattered in the trees and big fish darted through the pellucid depths.
