I found pieces of old horseshoes in the same place where, a couple of years ago, Randy found a military button from the 1904 Indian Wars. The shoes have a grove to hold the nails, so I know they are older than 1750s. Some square nails are still in the shoes, and square horseshoe nails are from the mid-1800s to very early 1900s. So I think these are probably from the same period as the button and bullet. They are probably artifacts from the 1904 Indian Wars. Pretty cool.
