About this map

The John Rains House stands as a notable landmark in this 2012 survey, situated within a densely developed landscape at the base of the San Gabriel foothills. This region shows a complex layering of suburban growth and industrial heritage, particularly evident in the presence of historic agricultural remnants like the San Antonio Winery, Flippi Winery, and Galleano Winery. These sites hint at the area's deep-rooted viticulture history, even as massive infrastructure like the Inland Empire Interchange and Ontario International Airport dominates the modern geography.

Residential communities such as Alta Loma, Etiwanda, and Guasti are interconnected by a grid of thoroughfares, including the historic 66. Water management is clearly defined by engineered channels for Cucamonga Cr and Day Cr, which traverse the settlements. From the open spaces of Whispering Lakes Golf Course to the industrial corridors along the Union Pacific railroad, the map captures a transition from traditional ranching and vineyards to a major logistical and transportation hub.
