This is a few days old now but... last weekend we attempted to drive over Hoodoo Pass to the NF Clearwater / Kelly Creek. As of Saturday 6/20 there was too much snow to get over the pass still. On the drive down we did pass the bulldozer that was headed up to plow the drift.
We just received a report today that the pass has been cleared and you can access the rivers from Superior, MT. Currently the Black Canyon is not accessible for trailers.
Give it a shot if you are looking to explore some fresh water!
