I've posted the current teaching opportunities in the California Community College system over at my blog for the Far West Section of the National Association of Geoscience Teachers, Teaching the Earth Sciences. Forgive me for shamelessly plugging the site every so often: It doesn't get a lot of traffic, but I think it has great deal of useful information available on teaching and geo-touring in the California-Nevada-Hawaii region. They sell an excellent selection of guidebooks, with the proceeds going to a scholarship fund for earth science students in the region.
Please also catch this important post on the need for support for a change in attitude by the University of California towards the earth sciences in their admission requirements. Earth Science has always taken a back seat to chemistry and physics, and yet is most vivid example of chemistry and physics at work in the real world. We need to support the teaching of the earth sciences at the secondary level.
