Central California is not a generally recognized subdivision of the state, it is just a personal definition I have made to serve the interests of this site. The region that results from this partition is unusually rich in famous places and beautiful scenery. Add to this the fact that I happen to live in this "state" and it is no wonder that I have so many panoramas to illustrate it.
Its northern boundary runs through the Golden Gate and Carquinez Strait, then through the Delta and across the Sierra Nevada between Sonora Pass and Yosemite. Thus, by my definition, San Francisco is in Central California but Marin is in Northern California. The deserts east of the Sierra crest are quite distinct and belong to my "state" of Southern and Eastern California.
The southern boundary follows an old geographic convention and runs from Point Conception along the crest of the Santa Ynez Range just north of Santa Barbara, through the knot of mountains around Tejon Pass, then east along the Tehachapi Range. From there it curves north to follow the Sierra crest all the way to Yosemite.
Most of this region is easily accessible from my home base in the East Bay and I take pictures here year around. Oddly enough, there are some areas very close to home (such as Oakland) for which I still have no panoramas!
