A few comments about the organization of field trips # 4 and # 6: In the past this

was one trip over two days (San Diego, 1996; Long Beach, 2012), but is now two

separate trips. The trips will use the same guidebook and visit essentially the same

stops as the earlier trips but in a different order. These trips will start in Bakersfield

each morning and return to Bakersfield each evening. At the end of this guidebook is

a map showing locations of present stops.

Field trip # 4 is a transect across the western Transverse Ranges and, for the most

part, is along Highways 166, 33, and 150. Field trip # 6 is a transect across the central

and western portions of the Transverse Ranges and, for the most part, is along

Highway 166, Interstate 5, and Highway 14.

The authors wish to thank the Geological Society of America for allowing the use of

the two figures on the guidebook cover and reprinting of Namson and Davis, 1988b,

with comments and replies, that appears at end of this guidebook.

Welcome to our field trip,

Jay Namson

Thom Davis

Stuart Gordon
