I'm not saying the axe head is fake, but because there were thousands of them carried by both Indians and whites, provided by the British, French and American trading companies, and the fact they are still being manufactured today in exactly the same way they were then, folded and forge welded, and the fact that the Lewis and Clark trail is a couple of thousand miles long going and coming, and was traveled by thousands of people carrying tomahawks that look exactly like that one, it's a tough call to even say for sure that it is even old, let alone carried by anyone associated with the L&C expedition. I didn't know your father's uncle, don't know the year he found it, don't know how old he was, don't know where he found it except somewhere along the trail. All that being said, I wish I did know your fathers uncle, I'd love to be able to sit and talk with him, he found some great stuff, and no doubt had great stories to go with it. All I'm pointing out is it's definitely a tough call to link the axe to anyone, except to say this, if the tomahawk was found at Fort Bragg, it's definitely, positively, not possible for it to have been lost by anyone on the Lewis and Clark expedition, they were never there. Fort Bragg is a town on the northern California coast that had an army garrison prior to the Civil War, and it's several hundred miles south of Fort Clatsop on the mouth of the Columbia River where Lewis and Clark wintered over in 1805/06. Again, I'm not saying the axe head is not the real thing, anything is possible, it's just that I'm trying to point out the "what if's" that are involved.
