Summary
[edit]DescriptionGaspar de Portolà Expedition Campsite plaque.jpg |
English: Plaque commemorating a campsite of the Gaspar de Portolá expedition, on Cañada Road near Redwood City, CA. The plaque reads:
Gaspar de Portolá Expedition Campsite The Gaspar de Portolá expedition camped twice near this marker. During Spain's initial colonial thrust into Alta California, the exploration party headed northward from San Diego searching for Monterey Bay. At first, they did not recognize the bay and continued to travel north. Turning east looking for a supply ship, they climbed Sweeney Ridge and on November 4, 1769, made the European discovery of San Francisco Bay. On November 5, they camped near here and traveled to San Francisquito Creek the next day. After some scouting, they reversed course to search once more for the elusive Monterey. On November 12, they again camped near this site at "a small lake". Dedicated by the Gaspar de Portolá Chapter National Society Daughters of the American Revolution September 7, 2019 A smaller plaque below the main one reads: PORTOLA MONUMENT BUILT BY E CLAMPSUS VITUS YERBA BUENA NUMBER I 7 SEPTEMBER 2019/6024 |
