2015 Map of Ontario

About this map

The dense academic landscape of Claremont defines the northwestern corner of this study, featuring an extensive cluster of institutions including Pomona College, Scripps College, and Harvey Mudd College. The map illustrates the suburban expansion of the Pomona Valley, where the grid-like residential developments of Upland and Ontario meet at the Los Angeles Co San Bernardino Co line. This boundary bisects a region characterized by specialized neighborhoods like Narod and Sunsweet, as well as infrastructure like Cable Airport. To the south, the terrain shifts toward the Chino Hills and Puente Hills, where the watercourses of Chino Cr and the San Antonio Cr Channel provide a drainage network for the surrounding communities of Chino and Montclair.
