Just ran it or I'd join you- sorry. There was a ranger stationed at Green Valley Lake if you start that way. I assume he was checking for chains but he waved us by. Please note that Van Dusen (2N09 I think) was closed when we were there Monday. You can get back out a couple of different ways- or just stay on 3N16 all the way out. It's only another 2 miles past Van Dusen I believe. We didn't have any problems but be careful in the beginning at higher elevation- there were a few icy patches you couldn't see.
Here is a map of the east side showing your routes.
