1966 Map of Cucamonga Peak

About this map

Cucamonga Peak towers over a landscape defined by the sharp transition from the steep San Gabriel Mountains to the developing citrus groves and vineyards of the Inland Empire. The southern portion of this mid-century survey captures the northward expansion of Alta Loma and Etiwanda, with purple revisions from 1973 showing the rapid spread of residential tracts. Education and transit are central to this growth, evidenced by the campus of Chaffey Union Jr College and the parallel tracks of the Atchison Topeka and Santa Fe and Southern Pacific railroads.
