Some info on cabin. The WMNF was supposed to start managing the cabin on a reservation basis this year for the cabin and would start locking the door. This does not appear to have happened yet. When I was up there several weeks ago, the cabin was in good shape, but there is no wood stove (its been gone for a few years. There is an outhouse. There are four wood floored bunks with ensolite pads attached on top of the wood inthe back room.
The water supply is a long trip from the cabin (towards the summit) and is off on a long side trail (which was marked) and way down the mountain. Either carry water up, melt snow (if there is some) or bring a large container to fill up to cut down on trips.
There really isnt any great camping spots nearby although there is a possiblity of some rough bumpy spots in the adjacent woods.
