From Stars & Stripes: "The weathered Winchester Model 1873 is in a case designed to capture the way it looked when park archaeologist Eva Jensen stumbled across it on a rocky outcrop above Strawberry Creek during an archaeological survey.
Based on its condition, experts believe the weapon might have been abandoned in the forest more than a century ago.
But nearly five years after its discovery, park officials still don’t know who it belonged to nor why it was left against the tree. No sales or ownership records have been found."
