I found this some time ago on the airline trail a few hundred yards downhill from the Madison Springs AMC hut. Other views:This shows a very classic patter of flaking, executed in a crude material.
There is a big difference in the wear of this side of the tip, versus the picture after next:
I am not holding it funny - that side is rounded off and relatively smooth.
So you tell me: who was doing what up there? Recall this from the pass between Adams and Madison.
