Legal places to find Trilobites or Ammonites in California?

[kwic13]

Hello! My first post here. I was just wondering if anyone knew of specific locals in order to find ammonites or trilobites in California? 

 

I found the website below somewhat useful, and have googled some of the locals on this area that have slightly pinpointed more specific areas, but I do know that sometimes fossils are only present on one part of one exposed cliff, and whatnot, and if I am going to go through the middle of nowhere, I don't want to not see fossils.

Anyways, I haven't quite chosen my road trip route yet, but I will start in Calexico, CA and end in San Francisco, CA. I will likely go to the Chocolate Mountains, up to Blythe, CA, then across the Mojave to Bakersfield, CA (passing by the Trilobite Wilderness), then through the Carrizo Plains, and then up to Pinnacles NP, and then hopefully end up in San Francisco.

 

If anyone knows a spot that isn't too inaccessible (I will have a 4WD), please let me know! Thank you.
