Afraid I won't be much help, but will share what very little I do know.
I see them whenever I go trout fishing in the Eastern side of the High Sierra's. Basically from Bishop to Bridgeport and always a mile or 2 in the backcountry away from the roads. Be careful of mtn lions & bears in some area's. Bring enough gun in other words. I take my 44 mag as back up.
A phone call to the various Eastern Sierra outfitters, Fish & Game (Bishop) & Forest Service may help.
Bishop is closest to L.A. / Orange co, so perhaps area's around Sabrina, North or South lake?!
