Pomona Valley

The Chino Hills are the southern boundary that separates the Pomona Valley from northern Orange County.

In contrast to much of the Greater Los Angeles Area, The Pomona Valley can get much hotter summers with high temperatures ranging from the triple digits.

Northern areas of the valley that contain the cities of Claremont, La Verne, and Upland have large Caucasian populations.

Central portions of the valley that contain the cities of Pomona, Montclair, Chino, and Ontario have large Hispanic populations.

Southern portions of the Pomona Valley such as Chino Hills, and Ontario Ranch contain rather large Asian populations.

Rancho Cucamonga, a city in the north west of the valley is very diverse, with large groups of Hispanics, Whites, Asians, and Blacks.
