I haven't been able to find anything on the missing plane either. I checked the NTSB monthly list and exactly nada there too. Maybe when the preliminary comes out, they'll at least list a last known position and course. Though it's been stated in the news stories that the pilot reported trouble and asked for vectors to Johnson Creek, that's about all.
I've flow piston airplanes through that area a few times and done a bit of hiking near there as well. Beautiful and desolate. But never during the winter months. This is one of those areas where a crashed airplane could go unnoticed for a long time, especially after a snow. I hope this doesn't turn out to be one of those...
