# Anyone know of a good, detailed San Andreas Fault map?

 P: 3 I live less than a mile from the SAFZ near Frazier Park, and would like to identify related surface features like escarpments, tuff outcrops, etc. After much Googling, I have found no maps that would help me locate the identified fault line locations within even 1000ft. None. Has anyone here seen any such maps that do not require $$or proprietary viewers?

You have to move around with the mouse to find them Thanks! That works quite well. Looks like a Google Maps with a fault-line overlay. It looks familiar; I must have come across this before but did not check it's good resolution. It proves that the volcanic tuff did originate right on the fault line. I wonder how old that is...

If you would like printed maps/posters, the USGS HQ at Menlo Park south of San Francisco have an excellent collection. Their prices are very affordable. On one of my visits there, I stocked up on a bunch of maps.
Even if you dont wanna buy maps its still a cool place to visit :)

Just curious, but how could you ascertain the origin of a tuff was right on the fault line from that image?

and not just that but it probably didnt originate in that area anyway
everything west of the SAF ( and some sections east of it, particularly around San Francisco, between the SAF, Calaveras and Heyward Faults) originated 1000's of km to the south. most of this material has been rafted along by the movement of the SAF and assoc faults and accreted onto the western side of the USA. These slices of crust are called Terranes and also Exotic Terranes
Do a google search on "exotic terranes north america" there is a wealth of good info.

From my university studies in geology, I recall that researchers have found original Gondwana Land rocks along the California region. Definately qualifies as an exotic terrane :)
