are guides
required there if you've never been? I had a guy telling me they were--maybe it was just "strongly recommended"
anyway, I too am really interested in checking out silverton, I hear it is really intense. I think I'd be inclined to hire a guide my first time
but make sure you dail in your handy-dandy snow-o-meter so you can make sure there is "fresh but not too much" lol! --just kidding Philips
