Barbour Fork opens June 16, there's a gate at the bottom. I've run Argentine, Kingston, and Jenny Creek in late June and not been able to get to the top of any of 'em because of snow. For the higher elevations, wheeling season is less than 3 months/year- by mid October it starts to get pretty dodgy again.
Yeah, maybe that's why we go to Utah so much...
