I was on a few trails there. I do not have the book that you have, so I can guess by the names.
The "Calcite Mine" trail is nice and scenic and ends in a good area for exploration but it is NOT difficult by any means. In it "difficult" (level 7) in my book, too (Southern California Backcountry Adventures) but it can be done a good stock SUV with a good driver. But it is a nice short trail that I really enjoyed.
The best trail in the area, for me, hands down, is the "South Coyote Trail". It even has a river crossing.
In Ocotillo Wells area, two great trails to run together are "Fish Creek-Sandstone canyon" trail and "Arroyo Seco del Diablo" trail.
There are lots of great trails in the area.
Thank you for your input Oleg. I recalled that book & the other one from the same series that was briefly published for the entire state but is no longer in print (Bruno has it).
Anyhow, I checked how much it is (~$150 <img src="/forums/images/graemlins/zombie.gif" alt="" />)!!! Wow! I'm sure it's worth it, but not easy to justify for the occasional wheeling trip to S.Cal. Anyhow, I also tried to find the trails you mentioned online and unfortunately there isn't too much detail (trail map, gps waypoints, etc.).
Do you have any additional details or online resources on them that you can share? Perhaps a scan or pic of those pages out of your book? I'd love to get a better idea so I can consider them properly.
As for the trails I've mentioned, I've narrowed it down to the following trails which are relatively close together, challenging & scenic.
More to come... <img src="/forums/images/graemlins/cheers.gif" alt="" />
