hi michael,
i read your posts on castle crags, good stuff. I know this reply is a little late but if you are still interested. I moved to Weed 5 years ago, for a year, in that year i experienced exactly what you were describing a secretive self preservationist attitude, and distrust for newcomers. But I went on with my business and established a dozen new routes in the gully behind 6 toe crack now known as "the Grotto". These are all single pitch routes but they are some of the best routes at the crags from 10a - 12d. I moved back a year ago thinking I wasn't as much of an outsider, yet this wasn't the case. Still locals either didn't have the info I was seeking or they weren't sharing. So again I got to work, added 2 more routes to The Grotto, and then got pointed in the direction of Castle Lake. Were an unfinished route started by a climber just passing through awaited, It took some work and 2 bolts but I finished that route "Shastafari" 12d and "Raw" next to it at 11d.
Then I turned my attention to Castle Dome's East face, I did the Dike route again just to check things out and because it's the finest route in NorCal. That day I hiked up the ramp past the Dike route were I came across a huge overhanging dihedral with a pin in it. Of coarse nobody new anything about it, didn't matter,
that now goes at 12c all gear "Castle Corner". Then another 4 routes next to it went up all high quality, and a second pitch which I haven't red pointed yet but it will be about 12a or b.
Anyway I started a website AlpineAddict.com were I will be documenting all the info. you are welcome to it or to share what you want. I'll be starting a winter ascent of Beck's Tower in a week or 2, and i've also been active at Ney Spring an awesome little local secret. Check out my site and if your coming down this way drop me a line.
