I'm planning my second run of the season through Black Bear and returning to Ouray via Imogene. I am open for either 7/30-31 Saturday or Sunday. Hit me up if you are in the area that weekend
It differs every year. There's been times almost all the trails were passible until mid-November. Other years some are closed by mid-September. There is still at least a few trails open in October most years. It's a lot less crowded which is a nice bonus too. I will be around all of October except for Trail Hero in St. George. Hit me up if you want to get some late season runs in
