Durango has one of the worst snow packs this year, despite getting a lot of snow earlier in the year. Last I heard Vallecito was in, but there isn't really a class IV warm up on that option. Animas is dead and locals have told me it has peaked. Piedra near Pagosa Springs has peaked.
The spring run off has been somewhat delayed due to a lack of warm weather. The class IV-V that is running would probably be 8 hours from you. South Saint Vrain near Loveland, CO. Upper, middle, and lower Poudre Narrows near Fort Collins, CO. And then you have Gore Canyon near Kremmling, CO.
History will be kind to me, for I intend to write it.
