I organized a DS trip a few years back and heard guys were still sledding up on Grey Creek Pass, I called the Grey Creek store and they said it was unpassable for at least another month. I found it hard to believe so tried the pass the weekend before our trip to make sure it was do-able. This was me end of June 09... Didn't make it through on the road, but the powerline trail was ok as it doesn't reach high elevations. A week later it was all gone and we had a great ride.
