Congrats on the awesome bull and thanks for sharing! Sometimes when all seems lost elk just appear.
In regards to skinning and gutting, carry paracord in your pack and tie legs to brush/trees in the direction you need them to go. Roll the elk on one side, then the other. Tie hind legs towards the head to get the rump. Use gravity as much as possible. Not a fan of the gutless method because I try to get as much meat as possible off my elk, but to each their own.
