Register today
to participate in the
22nd Annual International Conference
of the Anza Society.

In 1774, Anza was nearly defeated by the formidable desert that surrounds Calexico today.  Anza then returned in 1775 with 240 colonists and over 1000 livestock. Lack of water dictated a need to divide the expedition into three groups and send the cattle by another route.

Join us for a thought provoking and immersive experience in Calexico, March 9-12, 2017
