Did a quick trip from East Rosebud Fri/Sat just to check things out and have an easy weekend. Went in to the west side of Rainbow Lake, where the mosquitoes were in full force. They didn't seem nearly as bad just down at Rimrock Lake, but it was a bit more breezy there.
Spoke to a USFS trail ranger/maint. who said the trail is clear of snow to Dewey Lake, but heavy snow and drifts above there. Not too surprising, but should be much better than last year's epic snow conditions into August. She had cleared all deadfall and a lot of loose rock up to Dewey.
We did meet at least two parties who claimed they were going out for about a week, so I can only assume they were headed over the top. Some folks are going to it already, I guess.
