Inscription.  The Juan Bautista de Anza Expedition of 1775-1776 traveled with 240 settlers, soldiers, and others 1,800 miles from Sonora, Mexico to Monterey, California. Anza then traveled with a much smaller group to San Francisco and the East Bay to discover the origins of the water of both San Francisco Bay and the Central Valley, and to find a route eastward to the Sierra Nevada Mountains. On April 4, 1776, the explorers journeyed very close to this area, but they had to turn south back to Monterey due to the impenetrable marshes and waterways to the east in the Delta.

Future generations after Anza also found the Delta wetlands a hindrance to progress. They "fixed” that problem by diverting most of its water for use elsewhere, drying out the land for farming and development. In the future as land around Big Break Regional Shoreline is restored back to marshland, perhaps it will look similar to what Anza saw in 1776.
