There is no trail at Otter Lake.  We struggled along shore hopping from boulder to boulder. At one point about halfway from either end, we came apon this sight - a skeleton of a horse with its saddle still attached.  There is a story here and your imagination can come up with a good one. Why anyone would try to take a horse along the shore is beyond me.  

Near the eastern end of the lake we met the other half of the troop from Fargo, their "A" team.  They had humped it all the way from the northern end of the "Beaten Path" trail far to the north.
