Cal Poly Land: A Field Guide, January 1, 2002, pages 41-45. Edited by Steven Marx. (San Luis Obispo, CA: Cal Poly Foundation).
Cal Poly Lands located in San Luis Obispo County experience a collection of idyllic microclimates due to their geographical position relative to the Irish Hills and San Luis Range to the south and west, and the Santa Lucia Range to the east. These ridges create sheltered valleys that retard the persistent summer coastal fog common to neighboring communities to the west and the wide seasonal temperature variations of the Salinas and San Joaquin Valley north of the Cuesta Grade.
