About this map

Agricultural roots meet industrial expansion on this mid-century survey of the Inland Empire. The landscape is punctuated by the transition from viticulture, evidenced by the Cucamonga Winery (Historical Landmark) and the smaller Winery nearby, to heavy industry and defense. The massive Kaiser Steel Plant dominates the eastern section, while the Ontario International Airport and California Air Nat'l Guard facilities signal the region's increasing strategic importance.

Rail transport remains a vital backbone for these industries, with four major lines including the Pacific Electric and Atchison Topeka and Santa Fe traversing the valley. Small settlements like Rochester and Guasti appear as concentrated grids amidst the geometric patterns of vineyards and groves. Local community life is rooted in sites like the Louisa Guasti Sch and Laird Community Ch, while the southern end features the large Mira Loma Quartermaster Depot along the Union Pacific tracks.
