This might win for most romantic or most melancholy historical find of the year.
This Winchester Model 1873 was found by archaeologists just a-leanin' against this tree, where its owner supposedly left it years ago.
There are no other relics in the area to suggest what might have happened. There is only the fact that this expensive weapon was left in a way that suggested its owner would soon return, but he did not. The rest is up to your imagination.
