2018 Map of Guasti

About this map

Ontario International Airport dominates the central landscape of this Inland Empire survey, serving as a massive transit hub between the growing communities of Ontario, Rancho Cucamonga, and Fontana. This 2018 record shows the dense suburbanization that has transformed the valley floor, yet significant agricultural and industrial markers remain, such as the historic Guasti settlement and the smaller enclave of Champagne. The drainage patterns of Cucamonga Creek and Day Creek are shown as they channel runoff from the northern heights toward the Jurupa Mountains. Educational institutions like Platt College-Ontario and American Career College reflect the area's modern workforce development. At the northern edge, the legacy of rail infrastructure is visible in the Pacific Electric Trail, which follows the route of former electric lines through Alta Loma and Etiwanda. The map provides a detailed view of the complex freeway interchanges and residential street grids defining the San Bernardino and Riverside County border near Eastvale.
