I would also bet most people have not been up the east ( Middle on map) fork of the Chena that would be another place to check. Or loop around the state cabin site on way back or up? Stiles Cabin I think it is.
Leave C lakes, first stop Vally center, top off, rest room stop. :D
This is my first time on the site, so I didn't notice all the other messages; Angel Creek Lodge is a checkpoint for the Yukon Quest, so that trail might be of interest. It should be in good condition since I haven't been down the portion along the North Fork with my Landcruiser this winter. I've been on different sections of that trail from Angel Creek and up the North Fork ten or fifteen miles over the years, mostly in my Landcruiser, but not in the past two. Larry Voorhies traps the trail almost all the way to Eagle Summit, so it is usually in real good shape.
