The most thorough current source of information on the Anza expedition can be found at the Web De Anza site. Use the maps found there to locate your area of interest, then contact a local park for more information.

The journals of Anza and Font describe the many environments the expedition passed through on the way to the San Francisco bay. These include the saguaro-filled Sonoran desert, the cottonwood/willow riparian habitat along desert rivers and streams, the cold mountain passes of the lower Sierra Mountains of California, and finally the moist and fertile grasslands of the central coastline of California.

Father Font used an astronomical quadrant on the trip to fix the group's location so that the trail could be mapped and followed by others.
