OK, since no one else will I'll throw you a bone and give you a quick edjumacation. Stability is all relative. If you are asking which state "generally" has the most stable snowpack, most people will answer CA. Likewise, CO notoriously has the least stable snowpack. "In general", the more snow you have with temperatures near freezing, the more stability. Less snow, very cold temps = instability. That said, there are times when CA has extremely high avy danger, and due to the large amounts of snow, these avys can be huge. Fortunately for us, these periods are typically short-lived, and it's not uncommon to ride burly terrain a day or two after a dump of several feet that you wouldn't even consider in other places. But our snow is all Sierra Cement and not worthy by the standards of the high-and-dry Coloradans.
Sounds like I should do a west coast trip then. I don't want to have to wait till spring to get on some good lines here in Colorado. I have lot's of experience here in Colorado, and the general rule in steep bc is if you can't get it to slide before you drop in, then you don't drop in.
