Arroyo de San Joseph Cupertino This arroyo honoring San Joseph, patron saint of flight and students, was first discovered and traversed by Spanish explorers in 1769. On March 25–26, 1776 Colonel Juan Bautista de Anza made it his encampment no. 93, as mapped by his cartog- rapher Padre Pedro Font, before continuing on to the San Francisco Bay Area where he initiated steps to found a colony, a mission and a presidio.

The Story
This creek carries the name of San Joseph of Cupertino, the patron saint of flight and students, and its banks were traced by Spanish explorers in 1769. In March 1776 the expedition of Colonel Juan Bautista de Anza camped here—encampment No. 93 on Padre Pedro Font's map—while marching north to help found the mission, presidio, and colony that would become San Francisco. The arroyo gave the later town of Cupertino its name.
Why it matters
It marks a link in the Anza trail, the audacious overland trek that seeded Spanish settlement of the San Francisco Bay and reshaped the map of the American West.
The story behind this marker
AI contextThe era
The story of this arroyo reaches back into California's Spanish colonial era, a time when the land that is now Silicon Valley was known to Europeans only through the eyes of a handful of explorers and missionaries. In 1769 the first Spanish expeditions were pushing north through Alta California, mapping creeks and valleys and giving them the names of saints. This modest watercourse gained the name of San Joseph of Cupertino, honored as the patron saint of flight and of students — a name that would, centuries later, attach itself to a whole city.
By the 1770s, Spain was moving from exploration to settlement, determined to secure its claim on the Pacific coast by planting missions, presidios, and colonists. The San Francisco Bay, only recently sighted by Europeans, was the great prize to the north — a magnificent harbor that Spain intended to hold. The overland problem was how to get people there safely across hundreds of miles of unfamiliar country.
It was in service of that ambitious plan that a Spanish colonel and his cartographer priest made camp beside this creek in the spring of 1776.
People & events
The colonel was Juan Bautista de Anza, one of the most capable frontier leaders in Spain's American empire, and the man charged with leading settlers overland to the San Francisco Bay. Traveling with him was Padre Pedro Font, a Franciscan whose careful maps and diary would become one of the great records of the expedition. On March 25 and 26, 1776, they made this arroyo their encampment — number 93 in the long tally of stops that Font recorded as the party worked its way north.
The number itself tells the story of the journey's scale. To reach a creek in what is now Cupertino and call it the ninety-third camp is to grasp just how far these travelers had already come, day by day, from the south. And this was not merely a scouting trip: Anza was leading the effort to bring colonists to the bay, and from here the expedition pressed on toward its goal.
At the San Francisco Bay, Anza initiated the steps to found a colony, a mission, and a presidio — the seeds of the great city to come. The creek that had sheltered his camp for two nights kept the saint's name it had been given years earlier, and in time that name passed to the town that grew up around it.
Its place in the American story
This quiet arroyo is a link in the chain of the Anza expedition, one of the boldest overland treks in the history of Spanish North America. The journey that paused here helped bring the first colonists to the San Francisco Bay and set in motion the founding of the settlement that would become one of the world's great cities. What began as an encampment number in a priest's notebook became part of the founding story of San Francisco.
It is also a reminder of how much of the American West carries a Spanish signature. The saints' names on the creeks and towns, the routes of the old expeditions, the missions and presidios — all predate the United States' arrival in California by generations. To stand where Anza camped is to touch the deep colonial layer beneath the modern map.
That the name Cupertino now belongs to a center of the modern age gives the site a quiet poetry. A saint remembered as the patron of flight and of students lends his name to a valley that would become synonymous with invention. The through-line from a 1776 campsite to the present is a distinctly American kind of continuity.
If you visit
This is a landmark that asks you to read the landscape rather than tour a building. Find the arroyo and follow its course with your eye, imagining a Spanish expedition halting here for two nights in the spring of 1776, tents and animals gathered by the water while Padre Font noted it as camp ninety-three. The creek is ordinary at a glance, which is exactly what makes the history startling.
As you read the plaque — placed in 1968 and marking a California Registered Historical Landmark — notice how it braids together the saint's name, the explorers of 1769, and Anza's march toward the bay. It rewards a slow read, because every line points to something larger than the spot itself.
The real pleasure here is the contrast. You are standing in the heart of modern Silicon Valley, and yet the ground beneath you was mapped by a Spanish cartographer nearly two and a half centuries ago. For a road trip, the arroyo makes a fascinating first stop on the long trail of Anza's expedition northward — a chance to trace, in your own travels, a route that helped give rise to San Francisco.

This arroyo carries the name San José de Cupertino, given as Spanish explorers pushed north through California in 1769. In late March 1776, the expedition led by Colonel Juan Bautista de Anza camped along its banks while making its way to help found a settlement at San Francisco Bay. The little watercourse thus witnessed a pivotal moment in Spain's colonization of Alta California.
De Anza Expedition
Sunnyvale, CA
In 1775–1776, Lt. Colonel Juan Bautista de Anza led a Spanish expedition, authorized by King Carlos III, to colonize the San Francisco Bay Area.

Sunnyvale, CA · est. 1960
Martin Murphy Jr. reached California in 1844 as part of the first wagon train to haul across the Sierra Nevada, an arduous crossing that opened the overland route. Settling in the Santa Clara Valley, he founded Sunnyvale and built his home here from prefabricated lumber shipped around Cape Horn in 1849. The Murphy family lived on the property for more than a century, until the city acquired it in 1953.
Secundino Robles Adobe Site
Palo Alto, CA · est. 1969
In 1847, brothers Secundino and Teodoro Robles bought the sprawling Rancho Rincon de San Francisquito, more than four thousand acres, from José Peña. The original adobe had begun humbly as a sheep-herder's shelter tied to Mission Santa Clara. Secundino turned it into a lively social center of Mexican-era California, complete with a ring for the bull-and-bear contests popular in that day.
