Info required about Mt Diablo and Yosemite 5.7/5.8 grade climbs

Question
Hi Jeff
I need some information on good 5.7 or 5.8 climbs in mt diablo area ... I have left all my trad gear back home (India) ... so I would like to do some multi pitch routes ..2-3 pitches (or more) would be nice ... but which are bolted so that I do not need to purchase trad stuff...
Can u tell me good places to climb for mt diablo and Yosemite ...

I live in concord .. so both the places are pretty nearby.

Can u give me some info on above ?

Thanks

Answer
Nuwazish,
There are a few 5.5 -5.7 routes on Mt Diablo but are not very good this time of year. The rock is sandstone and tends to get soft and loose after rain. But you could check it out.  The Routes on Butt Rock are ok and there are a couple others but they are basically top rope climbs.

Yosemite has many routes. Try out the routes at Church Bowl, Swan Slab and Knob Hill. o to www.supertopo.com for lists of routes and some beta. There are also climbing guides for Mt Diablo you can get at REI in Concord.

Good Luck

Jeff
