About this map

Tres Pinos serves as the focal point of this mid-century survey, situated where the Tres Pinos Creek meets the broader alluvial plains. The landscape is defined by the convergence of several major land grants and ranching boundaries, including Santa Ana, Quien Sabe, and the Cienega de los Paicines. This period shows a rural educational network still intact, with the Santa Ana School, Enterprise Sch, Southside Sch, and Santa Anita School distributed across the valleys to serve the surrounding ranching community.

Transportation through the Santa Ana Valley follows established routes like the Airline Highway and Fairview Road. Significant recreational and agricultural landmarks are evident, such as Bolado Park and the Indart Ranch. The presence of a Gaging Sta on the San Benito River and numerous windmills scattered across the terrain near Swanson Bluff underscores the critical importance of water management in this California ranching corridor during the 1950s.
