Thanks for the help. I've been having trouble accessing the Fault Maps all day both through AOL and PacBell DSL. I fear it's from all the other people accesssing the Fault Map link as well! I could not recall where I had stored my big CA Fault Map and just found it a little while ago. You can bet with all this activity, it's going back up on my wall! I think, from looking at my big map just now, that the Oak Ridge and/or the San Cayetano are good guesses, although it does follow the Bailey Fault when I look at the map. Finally, I got an e-mail about ominous news regarding the (Sespe, I think) Hot Springs (just west of Fillmore) but it may have meant Mammoth, the message was so cryptic. I have to wait until Tuesday or Wednesday for additional info, but rest assured, geologically, we are in for some hot stuff! Thanks again! Beth
