NO. 673 SAN GREGORIO - Somewhere in this narrow valley, perhaps on this very spot, the Anza Expeditions of 1774 and 1775 made their camps. Water for the 240 people and over 800 head of stock on the 1775 march was obtained from a series of wells, deeper than the height of a man, dug into the sandy bottom of the wash.
