About this map

The Cucamonga Winery and the John Rains House anchor the northern landscape of this mid-century survey, representing the deep viticultural and ranching roots of Cucamonga. By the mid-1960s, the region was undergoing a massive industrial and transportation transformation, evidenced by the presence of the Steel Plant and Slag Dump near Fontana, and the massive Ontario Motor Speedway footprint. These features mark the shift from agricultural lands to heavy industry and high-speed infrastructure.
