Owens River Gorge Guidebook

Is there only there Owen River Gorge by Marty Lewis available?

And is there a big difference between the 9th and 10th edition? I see I can get the 9th shipped for $9 off amazon vs $30 for the 10th.

I'm doing my first trip out there in 3 weeks!

The new book is well worth the extra $21!! Unless you pay close attention to the descriptions/pictures it would be easy to start up the wrong route. So many new routes have been added.

On the other hand you can get by with the old book and MP. It's just more of a hassle.

Thanks for the advice. The 9th is published in 2000
So I'm gonna pick up the 10th.
